Narrated Muhammad ibn al-Muthanna: Ibn Abi 'Adi and 'Abd al-A'la narrated to us from Sa'id, from Qatadah, from Anas, that the Prophet of Allah, peace and blessings be upon him, did not raise his hands in any of his supplications except in the prayer for rain (al-istisqa'), until the whiteness of his armpits could be seen. However, 'Abd al-A'la said: "The whiteness of his armpit" or "the whiteness of his armpits" could be seen.
