It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that he said: I never saw the Prophet (peace and blessings be upon him) supplicating with his hands raised high, neither on his pulpit nor anywhere else. He (peace and blessings be upon him) would hold his two fingers level with his shoulders and supplicate. This hadith is sahih al-isnad (authentic in its chain), but the two Shaykhs did not record it.
