Hadith 89
Narrated Abd Allaah bin Muhammad: We were in the company of Aishah. When her food was brought in, al-Qasim stood up to say his prayer. Thereupon, Aishah said: I heard the Messenger of Allaah ﷺ say: Prayer should not be offered in presence of meals, nor at the moment when one is struggling with two evils (e. g. when one is feeling the call of nature. )
Hadith 485
Narrated Ubadah ibn as-Samit: We came to Jabir ibn Abdullah who was sitting in his mosque. He said: The Messenger of Allah ﷺ came to us in this mosque and he had a twig of date-palm of the kind of Ibn Tab. He looked and saw phlegm on the wall towards qiblah. He turned to it and scraped it with the twig. He then said: Who of you likes that Allah turns His face from him? He further said: When any of you stands for praying, Allah faces him. So he should not spit before him, nor on his right side. He should spit on his left side under his left foot. If he is in a hurry (i. e. forced to spit immediately), he should do with his cloth in this manner. He then placed the cloth on his mouth and rubbed it off. He then said: Bring perfume. A young man of the tribe stood and hurried to his house and returned with perfume in his palm. The Messenger of Allah ﷺ took it and put it at the end of the twig. He then stained the mark of phlegm with it. Jabir said: This is the reason you use perfume in your mosques.
Hadith 634
Ubadah bin al-Samit said: we came to Jabir bin Abdullah. He said: I (Jabir) accompanied the Messenger of Allah ﷺ in a battle. He got up to pray. I had a sheet of cloth upon me, and I began to cross both the ends, but they did not reach (my shoulders). It had fringes which I turned over and crossed the two ends, and bowed down retaining it with my neck lest it should fall down. Then I came and stood on the left side of the Messenger of Allah ﷺ. He then took and brought me around him and set me on his right side. Then Ibn Sakhr came and stood on his left side. he then took us with his both hands and made us stand behind him. The Messenger of Allah ﷺ began to look at me furtive glances, but I could not understand. When I understood, he hinted at me tie the wrapper. When the Messenger of Allah ﷺ finished the prayer, he said (to me): O Jabir. I said; Yes, Messenger of Allah. He said; if it (the sheet) is wide, cross both its ends (over the shoulders); if it is tight, tie it over your loins.
Hadith 1532
Jabir bin Abdullah reported the Messenger of Allah ﷺ as saying: Do not invoke curse on yourselves, and do not invoke curse on your children, and do not invoke curse on your servants, and do not invoke curse on your property, lest you happen to do it at a time when Allah is asked for something and grants your request. Abu Dawud said: This Hadith has a continuous chain of narrators, Ubadah bin Al-Walid bin Ubadah (did) met Jabir.
