"I said to 'Ata': 'What is the best time you think I should pray Al-'Atamah, either in congregation or on my own?' He said: 'I heard Ibn 'Abbas say: "The Messenger of Allah (ﷺ) delayed Al-'Atamah one night until the people had slept and woken up, then slept and woken up again. Then 'Umar got up and said: 'The prayer, the prayer!'" 'Ata' said: 'Ibn 'Abbas said: "The Messenger of Allah (ﷺ) came out, and it is as if I can see him now, with water dripping from his head, putting his hand on the side of his head. .'" I checked with 'Ata' how the Prophet (ﷺ) put his hand on his head, and he showed me the same way as Ibn 'Abbas had done. 'Ata' spread his fingers a little, then placed them with the tips of his fingers on his forehead, then he drew his fingers together on his head until his thumb touched the edge of the ear that is next to the face, then moved it to his temple and forehead, then he said: 'Were it not that I would impose too much difficulty for my Ummah, I would have commanded them to offer this prayer only at this time.'"
Sunan an-Nasa'i Book 6, Hadith 38
We went to Abu Dharr (Ghifari) in Rabadha and he had a mantle over him, and his slave had one like it. We said: Abu Dharr, had you joined them together, it would have been a complete garment. Thereupon he said: There was an altercation between me and one of the persons among my brothers. His mother was a non-Arab. I reproached him for his mother. He complained against me to Allah's Apostle (ﷺ). As I met Allah's Apostle (ﷺ) he said: Abu Dharr, you are a person who still has (in him the remnants) of the days (of Ignorance). Thereupon I said: Allah's Messenger, he who abuses (other) persons, they abuse (in return) his father and mother. He (the Holy Prophet) said: Abu Dharr, you are a person who still has (the remnants) of Ignorance in him They (your servants and slaves) are your brothers. Allah has put them in your care, so feed them with what you eat, clothe them with what you wear. and do not burden them beyond their capacities; but if you burden them (with an unbearable burden), then help them (by sharing their extra burden).
