It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When you are three people, then two of you should not whisper to each other excluding the third, because this will cause grief to the third."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that even today that scene is preserved before my eyes when the Holy Prophet (peace and blessings be upon him) was describing about a prophet whom his people had beaten, and he was wiping the blood from his face and kept saying: "O Lord! Forgive my people, for they do not know me." (This is a reference to the incident of Ta'if.)

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Guard yourselves against lying, for lying leads to sin and sin leads to the Fire. A person continues to lie and pursues falsehood until he is written with Allah as a «كذاب» . And adhere to truthfulness, for truthfulness leads to righteousness and righteousness leads to Paradise. A person continues to speak the truth until he is written with Allah as a «صديق» ."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Envy (desirous admiration) is not permissible except in two cases: one is the person whom Allah has granted wealth and He enables him to spend it in the right way, and the other is the person whom Allah has granted wisdom and he judges with it among the people and teaches it to others."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once we asked the Prophet (peace and blessings be upon him) about walking with a funeral procession. He (peace and blessings be upon him) said: "It should be at a pace less than running, and the funeral should be followed, not leading (the funeral should be ahead and those walking should be behind it)."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "He is not one of us who strikes his cheeks, tears his collar, and calls with the call of ignorance."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "O group of young men! Whoever among you has the ability to marry, he should get married, for marriage lowers the gaze and protects the private parts. And whoever is not able to marry, he should observe fasting, for fasting diminishes sexual desire."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that we used to participate in battles with the Prophet (peace and blessings of Allah be upon him), and there were no women with us. Once we said: O Messenger of Allah (peace and blessings of Allah be upon him)! Should we not get ourselves castrated? But the Prophet (peace and blessings of Allah be upon him) forbade us from doing so. Later, the Prophet (peace and blessings of Allah be upon him) permitted us, for a specific period, to marry women in exchange for garments. Then he recited this verse: «﴿يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُحَرِّمُوا طَيِّبَاتِ مَا أَحَلَّ اللّٰهُ لَكُمْ وَلَا تَعْتَدُوا إِنَّ اللّٰهَ لَا يُحِبُّ الْمُعْتَدِينَ﴾» [المائدة: 87] "O you who believe! Do not make unlawful the good things which Allah has made lawful for you, and do not transgress. Indeed, Allah does not like transgressors."

Abu Musa Hilali narrates from his father that a man was on a journey, his wife gave birth to a child, milk accumulated in her breasts, and the husband began to suck it. In the process, some of the milk went down his throat. That man came to Sayyiduna Abu Musa (may Allah be pleased with him) to ask about this issue. He said, "Your wife has become unlawful for you." Then he went to Sayyiduna Ibn Mas'ud (may Allah be pleased with him) and asked him about this issue. He replied, "The Messenger of Allah (peace and blessings be upon him) said: 'Only that suckling establishes prohibition which nourishes the flesh and strengthens the bones.'"

It is narrated from Sayyiduna Ibn Mas’ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) taught us the Khutbah al-Hajah in this way: «إِنَّ الْحَمْدَ لِلّٰهِ نَسْتَعِينُهُ وَنَسْتَغْفِرُهُ وَنَعُوذُ بِاللّٰهِ مِنْ شُرُورِ أَنْفُسِنَا مَنْ يَهْدِهِ اللّٰهُ فَلَا مُضِلَّ لَهُ وَمَنْ يُضْلِلْ فَلَا هَادِيَ لَهُ أَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ» “All praise is due to Allah, we seek help from Him and ask forgiveness from Him, and we seek refuge in Allah from the evil of our own selves. Whomever Allah guides, none can misguide, and whomever He lets go astray, none can guide. I bear witness that there is no deity except Allah, and that Muhammad (peace and blessings be upon him) is His servant and His Messenger.”Then he recited the following three verses: «﴿يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللّٰهَ حَقَّ تُقَاتِهِ وَلَا تَمُوتُنَّ إِلَّا وَأَنْتُمْ مُسْلِمُونَ﴾» [آل عمران: 102] “O you who believe! Fear Allah as He should be feared, and do not die except as Muslims.” «﴿وَاتَّقُوا اللّٰهَ الَّذِي تَسَاءَلُونَ بِهِ وَالْأَرْحَامَ إِنَّ اللّٰهَ كَانَ عَلَيْكُمْ رَقِيبًا﴾» [النساء: 1] “And fear Allah, through Whom you ask one another, and (respect) the ties of kinship. Surely Allah is ever watching over you.” «﴿اتَّقُوا اللّٰهَ وَقُولُوا قَوْلًا سَدِيدًا﴾» [الأحزاب: 70] “O you who believe! Fear Allah and speak words of appropriate justice.”
