COMMENTARY on 4:9
A. Yusuf Ali:

Translation:
Let those (disposing of an estate) have the same fear in their minds as they would have for their own if they had left a helpless family behind: Let them fear Allah, and speak words of appropriate (comfort). 515
Commentary:

515  It is a touching argument addressed to those who have to divide an estate. 'How anxious would you be if you had left a helpless family behind?' If others do so, help and be kind.
