Abu Musa reported:
I was in the company of Allah's Apostle ( صلی اللہ علیہ وسلم ) as he had been sitting in Ji'rana (a place) between Mecca and Medina and Bilal was also there, that there came to Allah's Apostle ( صلی اللہ علیہ وسلم ) a desert Arab, and he said: Muhammad, fulfill your promise that you made with me. Allah's Messenger ( صلی اللہ علیہ وسلم ) said to him: Accept glad tidings. Thereupon the desert Arab said: You shower glad tidings upon me very much; then Allah's Messenger ( صلی اللہ علیہ وسلم ) turned towards Abu Musa and Bilal seemingly in a state of annoyance and said: Verily he has rejected glad tidings but you two should accept them. We said: Allah's Messenger, we have readily accepted them. Then Allah's Messenger ( صلی اللہ علیہ وسلم ) called for a cup of water and washed his hands in that and face too and put the saliva in it and then said: Drink out of it and pour it over your faces and over your chest and gladden yourselves. They took hold of the cup and did as Allah's Messenger ( صلی اللہ علیہ وسلم ) had commanded them to do. Thereupon Umm Salama called from behind the veil: Spare some water in your vessel for your mother also, and they also gave some water which had been spared for her.
