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

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: "It is not permissible for anyone to say that I am better than Prophet Yunus (peace be upon him)."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) would leave out some days in admonition and advice, as he did not consider it good for us to become weary.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "No woman should touch her naked body with another woman, so that she describes her physical features to her husband in such a way as if he is seeing her with his own eyes."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) used to say that Allah has cursed the woman who plucks hair and the one who gets it plucked, the one who tattoos and the one who has herself tattooed, and the woman who files her teeth for beauty. When a woman named Umm Ya'qub from the tribe of Banu Asad heard this, she came to him and said, "By Allah! I have thoroughly searched the Mushaf between its two covers, but I have not found this command anywhere in it." Sayyiduna Ibn Mas'ud (may Allah be pleased with him) asked, "Did you find this verse in it: «﴿وَمَا آتَاكُمُ الرَّسُولُ فَخُذُوهُ وَمَا نَهَاكُمْ عَنْهُ فَانْتَهُوا﴾» [الحشر: 7] 'Whatever the Messenger gives you, take it, and whatever he forbids you from, abstain from it'?" She said, "Yes!" He said, "Then the Prophet (peace and blessings be upon him) has forbidden these things." The woman said, "What if the women of your household do this?" Sayyiduna Ibn Mas'ud (may Allah be pleased with him) replied, "Go and see." The woman went to his house, then came back and said, "I did not see anything objectionable there." He said, "If it were so, my wife would not remain with me."

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 be upon him), and the other I say from myself. The Prophet (peace and blessings be upon him) said: "Whoever dies in a state while associating partners with Allah, will enter Hell." And I say: Whoever dies in a state while not associating anyone with Allah, will enter Paradise.

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

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to supplicate: «اللّٰهُمَّ إِنِّي أَسْأَلُكَ الْهُدَى وَالتُّقَى وَالْعِفَّةَ وَالْغِنَى» "O Allah! I ask You for guidance, piety, chastity, and self-sufficiency (freedom from need before the creation)."

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: "Do not accumulate property, otherwise you will become engrossed in the world."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) performed a prostration of recitation at the end of Surah An-Najm, and all the Muslims also prostrated, except for one man from the Quraysh who took a handful of soil and brought it to his forehead and prostrated on it. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says that later I saw him killed in a state of disbelief.
