It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once a man said to the Prophet (peace and blessings be upon him) that he encountered a woman in one of the gardens of Madinah and did everything with her except intercourse. Upon this, Allah revealed this verse: «﴿وَأَقِمِ الصَّلَاةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِنَ اللَّيْلِ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّيِّئَاتِ﴾» [هود: 114] "Establish prayer at the two ends of the day and at some hours of the night. Indeed, good deeds erase bad deeds."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once a man came and asked in the presence of the Messenger of Allah, "When will the Night of Qadr be?" The Prophet (peace and blessings be upon him) said: "Which of you remembers that night which was turning red and white?" I said, "May my parents be sacrificed for you, I remember it. At that time, I had some dates in my hand and I was secretly eating sahur with them at the back of my saddle, and the moon was out at that time."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) cursed the one who consumes usury, the one who gives it, the one who witnesses the usurious transaction, and the one who records it.

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) asked us, "How would it be if you were a quarter of the people of Paradise and the rest of the communities made up the other three quarters?" The noble Companions (may Allah be pleased with them) replied, "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said, "What if you are a third of the people of Paradise?" The Companions (may Allah be pleased with them) replied, "That is more than before." The Prophet (peace and blessings be upon him) said, "What if you are half of the people of Paradise?" The Companions (may Allah be pleased with them) replied, "That is even more than before." The Prophet (peace and blessings be upon him) said, "On the Day of Resurrection, there will be one hundred and twenty rows of the people of Paradise, of which only your community will make up eighty rows."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once someone asked the Prophet (peace and blessings be upon him), "How will you recognize those members of your Ummah whom you have not seen?" He replied: "Their foreheads will be extremely bright and radiant due to the effects of ablution, just like a piebald horse."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says that I have recited seventy surahs after hearing them from the blessed mouth of the Prophet (peace and blessings of Allah be upon him), and no one can dispute with me regarding them.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once an Ansari man said something which expressed anger towards the Prophet (peace and blessings of Allah be upon him). My heart did not agree to inform the Prophet (peace and blessings of Allah be upon him) about it. I wish I could offer my family and all my wealth as ransom in exchange for this matter. The Prophet (peace and blessings of Allah be upon him) said: "May Allah's mercy descend upon Musa; he was troubled even more than this, but he remained patient." Then he said: "A prophet was denied by his people and was wounded because he brought Allah's commands. He was wiping 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)

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: "I will wait for you at the Pond of Kawthar. At that time, there will be a dispute before me regarding some people and I will be overpowered. I will say: 'O Lord! My companions?' It will be said: 'You do not know what innovations they introduced after you.'"

Masruq (may Allah have mercy on him) says that once Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said, and as soon as he said this, the color of his face changed and he said: He said it like this, or something close to this. (Proof of caution)

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Allah has not sent down any disease except that He has also sent down its cure; whoever knows it, knows it, and whoever remains unaware of it, remains unaware."
