Bahlool and Haroun

One day Haroun Rashid asked Bahlool, “What is Allah's greatest blessing?”

“Allah's greatest blessing is the mind. Khawaja Abdullah Ansari says in his supplication, 'O Allah! Those whom You gave intelligence, what else did You not give; those whom You didn't give understanding, what did You give?' In one reliable Hadith, when Allah decided to take back His blessings from His slaves, first of all He took their intellect away. Reason is amongst subsistence. It is sorrowful that Allah took this blessing away from me.”
