I usually cannot wake up to offer

Q: When a Muslim is busy doing an important task, like tending sheep and keeping them off a plantation while the due time of Salah (Prayer) has come, can he delay performing Salah until he passes the plantation?

A: He is permitted to delay Salah after its due time until he passes the plantation, but he still has to perform it within its margin of time before the next prescribed Salah is due. This way a balance will be kept between religious and worldly interests, i.e. keeping the plantation safe and sound and offering Salah on time. (Part No. 6; Page No. 147) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
