Explanation

It is not correct or proper for someone who possesses something to be bequeathed or clarified, to neglect it for a long time. Rather, one should record and write it as soon as possible. The longest period of time permitted for someone not to write a will, is one or two nights. That is why Ibn ‘Umar (may Allah be pleased with him) after hearing this prophetic advice used to check his will every night. He did so as to adhere to Prophet's command and state the rights. A will is of two types. 1. Recommended will that one writes regarding voluntary deeds and acts of worship. 2. Obligatory will that one makes regarding the mandatory rights, which have no proofs to confirm them after one's death. This is based on the juristic rule that what is required for the fulfillment of an obligation is obligatory. Ibn Daqīq El-Eid stated that this Hadīth addresses the obligatory types of will.
