Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: When the Prophet (peace and blessings be upon him) sent al-Ala' bin al-Hadrami (may Allah be pleased with him) to Bahrain, I went with him, and I saw three qualities in him; I do not know which of them is more amazing. We reached the seashore, and the people said: Say Bismillah and go in. So we said Bismillah and went in, and we crossed over, and the water wet nothing but the lower part of our camels' hooves. When we returned, we came to a desert land where we had no water. We complained to him, so he prayed two rak'ahs, then supplicated, and suddenly a cloud like a shield appeared, then it opened its mouths, and we drank and filled our water. He died after Abu Bakr (may Allah be pleased with him) sent him to Bahrain when Rabi'ah apostatised; Allah granted him victory over them, and they paid the zakah that they had been withholding. When he died, we buried him in the sand. Then, when we had gone a little way, we said: A wild beast might come and eat him. So we went back, but we did not find him.
