Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that in the blessed era of the Messenger of Allah (peace and blessings be upon him), the adhan was pronounced twice and the iqamah once, except that the (mu’adhdhin) would say « قَد قَامَتِ الصَّلَاةُ، قَد قَامَتِ الصَّلَاةُ» ‏‏‏‏ twice. So when we heard these words, we would perform ablution and set out. Muhammad says that Shu’bah said, I have not heard any hadith from Abu Ja’far except this hadith. From the chain of Imam Abu Bakr Bandaar, a narration is reported from Sayyiduna Ibn Umar (may Allah be pleased with them both) similar to the above.
