Narrated Abu Sa`id Al-Khudri:
A cloud came and it rained till the roof started leaking and in those days the roof used to be of the branches of date-palms. Iqama was pronounced and I saw Allah's Messengers prostrating in water and mud and even I saw the mark of mud on his forehead.
Narrated Ibn `Umar:
One of the wives of `Umar (bin Al-Khattab) used to offer the Fajr and the `Isha' prayer in congregation in the Mosque. She was asked why she had come out for the prayer as she knew that `Umar disliked it, and he has great ghaira (self-respect). She replied, "What prevents him from stopping me from this act?" The other replied, "The statement of Allah's Messenger (ﷺ) : 'Do not stop Allah's women-slaves from going to Allah's Mosques' prevents him."
Narrated Anas:
Zaid bin Thabit said, "We took the "Suhur" (the meal taken before dawn while fasting is observed) with the Prophet (ﷺ) and then stood up for the (morning) prayer." I asked him how long the interval between the two (Suhur and prayer) was. He replied, 'The interval between the two was just sufficient to recite fifty to Sixth 'Ayat."
Narrated Abu Huraira:
A black person, a male or a female used to clean the Mosque and then died. The Prophet (p.b.u.h) did not know about it . One day the Prophet (ﷺ) remembered him and said, "What happened to that person?" The people replied, "O Allah's Messenger! He died." He said, "Why did you not inform me?" They said, "His story was so and so (i.e. regarded him as insignificant)." He said, "Show me his grave." He then went to his grave and offered the funeral prayer.
