The time for the Qayloolah
Question: According to the Sunnah, is the time for the qayloolah (siesta) before or after the Zhuhrprayer?
Response: It is before they pray the Zhuhr prayer. (Then), after the (mid-day) heat has lessened, they can pray (the Zhuhr prayer). And the meaning of his (sal-Allaahu `alayhe wa sallam) saying:
((Perform the Zhuhr (prayer) when it is cool)), [Saheeh al-Bukhaaree, No.538] is that you should do the qayloolah before (the Zhuhr prayer).
And if he were to sleep after the Zhuhr prayer, then it is not considered as the qayloolah.
