(Second chain) Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) would sometimes fast so frequently that we would say, "Now he will not stop fasting," but then he (peace and blessings be upon him) would leave fasting for such a long period that we would think, "Now he will not fast." And since he (peace and blessings be upon him) arrived in Madinah Munawwarah, he did not fast for any entire month except Ramadan.
