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: "For each one of you, a companion from among the jinn and a companion from among the angels has been appointed." The noble Companions (may Allah be pleased with them) asked: "O Messenger of Allah (peace and blessings be upon him)! Even with you?" He replied: "Yes! But Allah has helped me against him, so now he only commands me to speak the truth."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that we were sitting in the Mosque of Khayf on the night of 'Arafah—which was before the Day of 'Arafah—when we sensed the sound of a snake. The Prophet (peace and blessings be upon him) said: "Kill it." We stood up, and it slipped into a hole. A spark was brought and the hole was set on fire. Then we took a stick and started poking the hole with it, but we did not find the snake. The Prophet (peace and blessings be upon him) said: "Leave it; Allah has saved it from your harm just as He has saved you from its harm."

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? The Prophet (peace and blessings of Allah be upon him) forbade us from doing so.

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 the Prophet (peace and blessings be upon him) drew a square, then drew another line in the middle of it, and on the right and left of this middle line he drew some more lines, and he drew one line outside the square. He said to the noble Companions (may Allah be pleased with them): "Do you know what this is?" The Companions (may Allah be pleased with them) replied: Allah and His Messenger know best. He said: "The line in the middle refers to a human being, the lines on its right and left are the diseases that keep attacking a person; if one misses, another hits. The square refers to a person's death which surrounds him, and the outer line refers to hope."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once a man kissed a strange woman, then, feeling remorseful, he came to the Prophet (peace and blessings be upon him) to ask about its expiation. 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." He asked: O Messenger of Allah (peace and blessings be upon him)! Is this command specific to me? He replied: "No, rather this command is for every person of my Ummah who commits such an act."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Let not Bilal's call to prayer prevent you from eating the pre-dawn meal (suhoor), for he gives the call to prayer early so that those who are performing the night prayer may return and those who are sleeping may wake up (and eat suhoor). The true dawn does not appear like this," (the narrator joined his hands and raised them), "rather, it appears like this," and the narrator separated his two index fingers to demonstrate.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Behold, those who engage in excessive argumentation have perished," and he said this three times.

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) used to sit between the two rak'ahs as if he were sitting on a hot stone. I asked, "Until standing up?" He replied, "Yes!"

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) was returning from Hudaybiyyah at night, and we camped on soft ground. The Prophet (peace be upon him) said: "Who will keep watch over us? (Who will wake us up for Fajr?)" Sayyiduna Bilal (may Allah be pleased with him) offered himself. The Prophet (peace be upon him) said: "What if you also fall asleep?" He replied: "I will not sleep." Coincidentally, he too fell asleep until the sun had risen and so-and-so companions woke up, among them was Sayyiduna Umar (may Allah be pleased with him). He woke everyone up, and the Prophet (peace be upon him) also woke up and said: "Do as you used to do" (perform the prayer as usual). When the people had done so, he said: "If any of you sleeps or forgets, then do likewise."
