It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once I presented myself in the court of the Messenger, and the Prophet (peace and blessings be upon him) had a severe fever. I touched him and asked: O Messenger of Allah (peace and blessings be upon him)! Do you also get such a severe fever? He said: "Yes! I get fever equal to that of two men among you." I said: Then will you also receive double the reward? He said: "Yes! By the One in Whose hand is my soul, there is no Muslim on the face of the earth who is afflicted with any hardship—whether it is illness or something else—and Allah does not, because of it, shed his sins just as a tree sheds its leaves."

The previous hadith is also narrated through this second chain of transmission.

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says: Safeguard this Qur'an, for it slips away from people's hearts faster than a camel escapes from its rope. And he said that the Messenger of Allah (peace and blessings be upon him) said: "None of you should say, 'I forgot such-and-such verse,' rather he should say, 'It was made to be forgotten by me.'"

Sayyiduna Ibn Mas’ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“The blood of a Muslim who testifies that there is no deity except Allah and that I am the Messenger of Allah is not lawful, except in one of three cases: if he commits adultery while being married, or if he kills someone and retribution is required, or if he abandons his religion and separates from the community.”

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that when we used to sit in Tashahhud with the Prophet (peace and blessings be upon him), we would say: "Peace be upon Allah from His servants, peace be upon Jibreel, peace be upon Mika'il, peace be upon so-and-so and so-and-so." When the Prophet (peace and blessings be upon him) heard us saying this, he said: "Allah Himself is the embodiment of peace, so when any one of you sits in Tashahhud, he should say: «التَّحِيَّاتُ لِلّٰهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللّٰهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللّٰهِ الصَّالِحِينَ - فَإِذَا قَالَهَا أَصَابَتْ كُلَّ عَبْدٍ صَالِحٍ فِي السَّمَاءِ وَالْأَرْضِ - أَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ» 'All verbal, physical, and financial acts of worship are for Allah alone. O Prophet (peace and blessings be upon him)! May Allah's peace, mercy, and blessings descend upon you. Peace be upon us and upon the righteous servants of Allah.' When he says this phrase, it will include every righteous servant in the heavens and the earth. I bear witness that there is no deity except Allah and that Muhammad (peace and blessings be upon him) is His servant and Messenger." After this, he may supplicate for whatever he wishes."

Sayyiduna Ibn Mas’ud (may Allah be pleased with him) says that whoever wishes to meet Allah tomorrow on the Day of Resurrection in a state of Islam, he should be regular in offering these obligatory prayers whenever they are called for, because they are among the ways of guidance (Sunan al-Huda), and Allah has prescribed the ways of guidance for your Prophet. Each one of you has a mosque in his house, but if you start praying in your houses as these people who stay behind pray in their houses, then you will have abandoned the Sunnah of your Prophet, and when you abandon the Sunnah of your Prophet, you will go astray. And I have seen that only the hypocrite, whose hypocrisy was well known, would stay behind from the congregational prayer. I have also seen that a man would be brought to the mosque supported by two men and would be made to stand in the row. And the Prophet (peace and blessings be upon him) said:“Whoever performs ablution and does it well, then sets out to any mosque, every step he takes will raise him one degree, or one sin will be forgiven, or one good deed will be written for him.”On this basis, we used to take small steps, and the virtue of praying in congregation is twenty-five times greater than praying alone.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) — who is truthful and believed — told us this hadith: "The creation of each one of you is gathered in the womb of his mother for forty days, then he is a clot of blood for the same period, then a lump of flesh for the same period, then an angel is sent to him and breathes the soul into him. Then he is commanded with four things: his provision, his lifespan, his deeds, and whether he will be wretched or blessed. By the One besides whom there is no deity! One of you may perform the deeds of the people of Paradise until there is only a cubit between him and Paradise, but what has been written overtakes him, and he performs the deeds of the people of Hell and thus enters it. And one of you may perform the deeds of the people of Hell until there is only a cubit between him and Hell, but what has been written overtakes him, and he performs the deeds of the people of Paradise and thus enters it."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says that there are two statements: one I heard from the Prophet (peace and blessings of Allah be upon him), and the other I say from myself. The Prophet (peace and blessings of Allah be upon him) said: "Whoever dies in such a state that he does not associate anyone with Allah, he will enter Paradise." And I say that whoever dies in such a state that he associates someone with Allah, he will enter Hell.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) asked the companions (may Allah be pleased with them): "Who among you is such that he loves the wealth of his heir more than his own wealth?" The companions (may Allah be pleased with them) replied: O Messenger of Allah! There is none among us who would love the wealth of his heir more than his own wealth. The Prophet (peace and blessings be upon him) said: "Remember! There is none among you who does not love the wealth of his heir more than his own wealth. Your wealth is only that which you have sent ahead, and your heir's wealth is that which you have left behind."

Also, once he asked: "Whom do you consider to be the strongest wrestler among you?" We replied: The one whom no one else can overpower. The Prophet (peace and blessings be upon him) said: "No, the strongest wrestler is the one who controls himself at the time of anger."

Similarly, once he asked: "Whom do you consider to be «رقوب» among you?" We replied: The one who has no children. He said: "No! 'Raqeeb' is the one who has not sent any of his children ahead."

Harith bin Suwaid says that once Sayyiduna Ibn Mas’ud (may Allah be pleased with him) narrated two hadiths to us, one from himself and one from the Prophet (peace and blessings be upon him). Sayyiduna Ibn Mas’ud (may Allah be pleased with him) said: A believer considers his sins as if he is sitting at the foot of a mountain and fears that the mountain may fall upon him, while a wicked person considers his sins as if a fly sat on his nose, he waved it away and it flew off. And the Prophet (peace and blessings be upon him) said:“Allah is more pleased with the repentance of any one of you than that person who, during a journey, passes through a deserted and deadly area, and he has a riding animal with him on which is his food and drink, his provisions and all his necessities, and suddenly they are lost. He goes out in search of them, and when he feels that his death is near but does not find the animal, he says in his heart: I will return to the place where my camel was lost, and there I will die. So he returns to his place, and upon reaching there, he falls asleep. When he wakes up, he finds his riding animal standing by his head, on which are his food, drink, provisions, and all his necessities.”
