It is narrated from Imam Jafar ibn Muhammad Al-Sadiq (a.s) by 'Ammar al-Sabati that He said: "When you stand for a mandatory prayer, give the adhan and the iqamah, and separate between the adhan and the iqamah with sitting, speaking, or tasbih (glorification of Allah (swt))." He (Ammar) asked: "What is the minimum that suffices between the adhan and the iqamah in terms of speech?" Imam (a.s) replied: "Saying 'Alhamdulillah' (All praise belongs to Allah (swt))."
