Usama bin Zaid (RA) reported that when Allah's Messenger (ﷺ) came to the valley where the rich (people of Makkah) used to get down, he got down and urinated (and he did not mention about pouring water); he then called for water and performed a light ablution. I said: Messenger of Allah, the prayer. Thereupon he said: Prayer awaits you ahead.
Ibn Abbas (RA) reported: A woman lifted up her child and said: Messenger of Allah, would the child be credited with having performed the Hajj? Thereupon he said: Yes, and there would be a reward for you.
