What advice did the Prophet Muhammad (saw) give to the people of Quba' regarding prayer when the hot sun affects their young weaned camels?
 Zaid b. Arqam reported that the Messenger of Allah (may peace be upon him) went out to the people of Quba' and saw them observing prayer; upon this he said:                      The prayer of the penitent should be observed when the young weaned camels feel heat of the sun.
