It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed the soul quickly grows weary, and none of you knows how long his term (of life) will be. So let him take on of worship only as much as he is able, then let him persist in it, for the most beloved of deeds to Allah is that which is done constantly, even if it is little."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Ishaq except al-Jarud bin Yazid, and Ibn Ishaq is alone in narrating it."
It is like this (al-Khadir bin Akhram) in the Dar al-Haramayn edition; the correct form is probably "Asram", and the editor of the Dar al-Haramayn edition pointed this out.
