When the elder brother witnessed the love and respect that his younger brother had for the blessed hair of Rasulullah (sallallahu ‘alaihi wasallam), he proposed, “Why don’t you take all three strands of hair in exchange of your share of the inheritance?” Out of love for Rasulullah (sallallahu ‘alaihi wasallam), the younger brother agreed. Accordingly, the elder brother took all the wealth of the estate while the younger brother took the three strands of hair.
The younger brother placed them in his pocket with utmost respect. Thereafter, he would continuously take them out of his pocket, gaze at them with love and recite durood upon Rasulullah (sallallahu ‘alaihi wasallam). He would then return them to his pocket.
After some period of time had passed, all the wealth of the elder brother had depleted, whereas the younger brother was granted abundant wealth by Allah Ta‘ala. After some time, however, the younger brother passed away.
After he left this world, a pious person had a dream in which he saw the younger brother together with Rasulullah (sallallahu ‘alaihi wasallam). Rasulullah (sallallahu ‘alaihi wasallam) addressed the pious person and said, “Tell the people that if anyone has a need from Allah Ta‘ala, he should go to the grave of this person (referring to the younger brother) and make du‘aa to Allah Ta‘ala to fulfill his need. His needs will be fulfilled.” People would thereafter come to the grave of this brother in order to make du‘aa, until even those who would be passing by on their conveyances would dismount and walk on foot out of respect before reaching the grave.
