Sahih Muslim Book 55, Hadith 50
← Previous Hadith Abdullah b. 'Umar reported that the people encamped along with Allah's Messenger (ﷺ) in the valley of Hijr, the habitations of Thamud, and they quenched their thirst from the wells thereof and kneaded the flour with it. Thereupon Allah's Messenger (ﷺ) commanded that the water collected for drinking should be spilt and the flour should be given to the camels and commanded them that the water for drinking should be taken from that well where the she-camel (of Hadrat Salih) used to come.

Sahih Muslim Book 55, Hadith 49 Next Hadith → One who makes efforts (for earning to be spent) on a widow and the destitute is like a striver in the cause of Allah, and I think he also said: He is like one who constantly stands for prayer and observes fast without breaking it.
