«يا معشر الأنصار! أمسكوا عليكم أموالكم لا تعمروها فإنه من أعمر شيئا حياته فهو له حياته وموته»
The Prophet (peace and blessings be upon him) said:
"O Ansar! Keep your wealth for yourselves and do not give it away as 'umra (a lifetime grant), for whoever gives something as 'umra for a lifetime, it becomes the property of the one it was given to, both in his life and after his death."
