From Sahih Muslim (Hadith 1434):
Jarir b. Abdullah is reported to have said:We were sitting with the Messenger of Allah (ﷺ) that he looked at the full moon and observed: You shall see your Lord as you are seeing this moon, and you will not be harmed by seeing Him. So if you can, do not let -yourselves be overpowered in case of prayer observed before the rising of the sun and its setting, i. e. the 'Asr prayer and the morning prayer. Jarir then recited it:" Celebrate the praise of thy Lord before the rising of the sun and before Its setting" (xx)
