Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
Look at the concept of trust and see how lightly we treat it whereas the Hadeeth speaks so highly of it. A person who does not have trustworthiness then really he does not have complete Imaan. Nabi (sallallahu ‘alaihi wasallam) has equated amaanat (trust) so closely with Imaan that as though without it one does not have a place in Islam.
