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: "At one time I intended to order a man to lead the people in prayer, and then order (some men) concerning those who do not join us for Jumu'ah, that their houses be set on fire."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that on the occasion of Laylat al-Jinn, two men among them stayed behind and said, "We will perform the Fajr prayer with the Prophet (peace and blessings be upon him)." The Prophet (peace and blessings be upon him) asked me, "Abdullah! Do you have water with you?" He replied, "I do not have water, but I do have nabidh in a vessel." The Prophet (peace and blessings be upon him) said, "This is pure dates and it is purifying as well." Thus, the Prophet (peace and blessings be upon him) performed ablution with it.

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: "At one time I intended to order a man to lead the people in prayer, and then to go to those who do not join us for the Friday prayer and order that their houses be set on fire."

Qasim narrates from his father that once Walid bin Uqbah delayed the prayer. Seeing this, Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) stood up, gave the iqamah, and led the people in prayer. Walid sent a message to him asking,“Why did you do this? Have you received any order from the Commander of the Faithful regarding this matter, or have you invented something new?”He replied,“Neither have I received any order from the Commander of the Faithful, nor have I invented anything new. But Allah and His Messenger do not want us to wait for you for our prayer while you are busy with your own affairs.”

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) went out to relieve himself and said to me, "Bring me three stones." I was able to bring two stones and a dry piece of dung. The Prophet (peace and blessings be upon him) took the two stones and threw away the piece of dung, saying: "This is impure."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says that I have fasted thirty days of Ramadan with the Prophet (peace and blessings of Allah be upon him) more frequently than I have fasted twenty-nine (29) days.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said to me: "Abdullah! Do you have any water with you?" I replied, "No." The Prophet (peace and blessings be upon him) asked, "What is in this vessel?" I replied, "Nabidh (a drink made from dates or raisins soaked in water)." The Prophet (peace and blessings be upon him) said, "Show it to me; this is both a drink and purifying." Then the Prophet (peace and blessings be upon him) performed ablution with it and led us in prayer.

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 be upon him), and there were no women with us. Once we said: O Messenger of Allah! Should we not get ourselves castrated? The Prophet (peace and blessings be upon him) forbade us from doing so. Then he recited this verse: «﴿يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُحَرِّمُوا طَيِّبَاتِ مَا أَحَلَّ اللّٰهُ لَكُمْ . . .﴾» [المائدة: 87] "O you who believe! Do not make unlawful the good things which Allah has made lawful for you."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) prescribed, in the blood money for accidental killing, twenty bint makhad, twenty male ibn makhad, twenty bint labun, twenty hiqqah, and twenty jaz’ah.

Benefit: These are terms used by jurists, according to which bint makhad or ibn makhad refers to a camel that has entered its second year, bint labun refers to a she-camel that has entered its third year, hiqqah to one in its fourth year, and jaz’ah to a she-camel in its fifth year.

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: "Whoever sees me in a dream should be certain that he has truly seen me, for Satan cannot take my form or appearance."
