It is reported about Sayyiduna Bilal (may Allah be pleased with him) that on Friday he would give the call to prayer (adhan) for the Prophet (peace and blessings be upon him) when the shadow had become the length of a sandal strap, when the Prophet (peace and blessings be upon him) had sat down on the pulpit.
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Abd al-Rahman bin Sa'd bin Ammar, who is da'if (weak).
