Why do we declare the one who abandons prayer a disbeliever, but not the one who withholds zakah?

Question : You heard his words. He said: Why do we declare the one who abandons prayer a disbeliever, but not the one who withholds zakah?

Answer : The answer: Listen, O Sa'd. Imam Ahmad said, in one of the narrations from him: Whoever abandons any of the five pillars of Islam is a disbeliever. According to this narration, the one who withholds zakah is a disbeliever, the one who abandons fasting is a disbeliever, and the one who abandons Hajj is a disbeliever. This is because Islam is built upon these foundations, so if one of these foundations is lost, Islam collapses.
However, the correct view is that one is not declared a disbeliever except for abandoning prayer alone, as 'Abdullah ibn Shaqiq said. The statement of the Prophet (peace and blessings be upon him) regarding the owner of silver who does not pay its zakah, where he said: then he will see his path, either to Paradise or to the Fire, indicates that he is not a disbeliever. Because if he were a disbeliever, he would have no path to Paradise. We do not say that there is evidence indicating his disbelief, nor is there evidence indicating his faith.
