It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Once Satan passed by me, I caught him and began to strangle him, his tongue came out until I felt the coolness of his tongue on my hand, and he began to say, 'You have caused me great pain, great pain.'"

Once Alqama and Aswad both came to the service of Sayyiduna Ibn Mas'ud (may Allah be pleased with him). When the time for prayer came, Alqama and Aswad stood behind him. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) took their hands and made one stand on his right side and the other on his left side. Then, when both of them bowed (in ruku'), they placed their hands on their knees. Sayyiduna Ibn Mas'ud (may Allah be pleased with him), seeing this, struck their hands and joined his own hands together, interlacing his fingers, and placed both hands between his thighs, and said: "I saw the Prophet (peace and blessings be upon him) doing it this way." Benefit: This act is called «تطبيق» , and in the beginning, this was the method of ruku'. Later, this ruling was abrogated, but Sayyiduna Ibn Mas'ud (may Allah be pleased with him) did not accept its abrogation until the end.

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

Khameer bin Malik says that once a government order was issued that the Qur'anic manuscripts should be changed (so that no arrangement other than the copies compiled by Sayyiduna Uthman Ghani, may Allah be pleased with him, should remain). When Sayyiduna Ibn Mas'ud, may Allah be pleased with him, found out, he said: Whoever among you can hide his copy, let him hide it, because whoever hides something will come with it on the Day of Resurrection. Then he said: I have recited seventy surahs from the blessed mouth of the Prophet (peace and blessings of Allah be upon him). Should I abandon those things which I have obtained from the blessed mouth of the Prophet (peace and blessings of Allah be upon him)?

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once two men named Aqib and Sayyid came from Najran. They came with the intention of having a mutual imprecation (mubahala) with the Prophet (peace and blessings be upon him). One of them said to the other, "Do not engage in mubahala (and mutual cursing) with him, because if he is truly a Prophet and he sends a curse upon us through mubahala, then neither we nor our descendants will ever succeed." So both of them came to the service of the Prophet (peace and blessings be upon him) and said, "We will not do mubahala with you. We are ready to give you whatever you demand, just send with us a trustworthy man." The Prophet (peace and blessings be upon him) said, "I will send with you such a trustworthy man who truly deserves to be called trustworthy." Upon hearing this, the noble Companions (may Allah be pleased with them) started raising their heads and looking (in anticipation). Then the Prophet (peace and blessings be upon him) said, "O Abu Ubaidah bin Al-Jarrah! Stand up." When both of them were about to leave, the Prophet (peace and blessings be upon him) said, "He is the trustworthy one of this Ummah."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that when the Prophet (peace and blessings of Allah be upon him) would lie down on his bed to sleep, he would place his right hand under his cheek and would supplicate: «اللّٰهُمَّ قِنِي عَذَابَكَ يَوْمَ تَجْمَعُ عِبَادَكَ» "O Lord! Save me from the punishment of the Day when You will gather Your servants."

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

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) would turn to the right and to the left in such a manner while saying salam that the whiteness of his blessed cheeks would become visible.

Sayyiduna Ibn Mas’ud (may Allah be pleased with him) narrates 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 in Whose hand is the soul of Abdullah, one of you may do the deeds of the people of Paradise until there is only a cubit between him and it, but what has been written overtakes him and he does the deeds of the people of Hell and enters it. And one of you may do the deeds of the people of Hell until there is only a cubit between him and it, but what has been written overtakes him and he does the deeds of the people of Paradise and enters it.”

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) taught me the words of Tashahhud just as he would teach a surah of the Noble Qur'an, while my hand was in the blessed hand of the Prophet (peace and blessings be upon him): «التَّحِيَّاتُ لِلّٰهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللّٰهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ 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 you)! Peace be upon you, and the mercy and blessings of Allah descend upon you. Peace be upon us and upon the righteous servants of Allah. 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." As long as the Prophet (peace and blessings be upon him) was among us, we used to say these words. When the Prophet (peace and blessings be upon him) passed away, we started saying «السَّلَامُ عَلَى النَّبِيِّ» .
