What is the basis of the advice the Prophet Muhammad (peace be upon him) gave to the people concerning acts of worship?
 'A'isha reported that the Messenger of Allah (may peace be upon him) had a mat and he used it for making an apartment during the night and observed prayer in it, and the people began to pray with him, and he spread it (the mat) during the day time. The people crowded round him one night. He (the Holy Prophet) then Eaid:                      O people, perform such acts as you are capable of doing, for Allah does not grow weary but you will get tired. The acts most pleasing to Allah are those which are done continuously, even if they are small. And it was the habit of the members of Muhammad's (may peace be upon him) household that whenever they did an act they did it continuously.
