A'isha (Allah be pleased with her) reported:The Messenger of Allah (ﷺ) did not observe fast in any month of the year more than in the month of Sha'ban, and used to say: Do as many deeds as you are capable of doing, for Allah will not become weary (of giving you reward), but you would be tired (of doing good deeds) ; and he also said: The deed liked most by Allah is one to which the doer adheres constantly even if it is small
