Abdur Rahman Ibn Ustaaz Azam
When Shaykh Abdur Rahman went to visit the grave of Nabi Hud (A.S.) some of his companions asked him to be their guest. They placed food before him but he refused to eat. They stated “Shaykh the food has been prepared for no-one else but yourself.’ He replied indicated to a bird, “”””This green bird has told me that there is doubt in this food as to whether it is halal or not.” The matter was looked into and it was as the bird had warned.
