It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with both of them) that staying in the valley of Muhassab is not something necessary. Rather, it is just a coincidental place where the Messenger of Allah (peace be upon him) stayed. Imam Abu Bakr (may Allah have mercy on him) says that the meaning of Sayyiduna Ibn Abbas’s (may Allah be pleased with both of them) statement is that staying in the valley of Muhassab is not obligatory upon people. In this way, he has negated something, even though it is permissible, as I have mentioned in the title of this chapter, because it is certain that staying in the valley of Muhassab is an action, and the name of the valley, Muhassab, is applied to this action (which has been negated, that Muhassab is not something). Even though this action is permissible, it is not obligatory.
