One of the works on this subject is his “al‐Fatwaa al‐Hamawiyyah” which he wrote as an answer to a question presented to him. In it, he was asked what the scholars and Imaams of the religion say concerning the Aayaat and the Ahaadeeth of the Si/aat, or the attributes and characteristics of Allah.

This is a useful book talks about how a fasting Muslim should spend his day in Ramadan. This is regarding deeds by which he abides during his day. No doubt he should be eager to instill the good morals into himself while performing this great rite. He should not forget to ask Allah when he breaks his fasting, for Allah promised that he answers the fasting Muslim’s invocation when he breaks his fast. He should remember that it is highly recommended to perform Qiyam (supererogatory prayers at night) to get his sins forgiven.
