أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنَا يَحْيَى بْنُ عَلِيِّ بْنِ يَحْيَى بْنِ خَلاَّدِ بْنِ رِفَاعَةَ بْنِ رَافِعٍ الزَّرْقِيُّ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، عَنْ رِفَاعَةَ بْنِ رَافِعٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم بَيْنَا هُوَ جَالِسٌ فِي صَفِّ الصَّلاَةِ الْحَدِيثَ ‏.‏

"Then Tashhad, then say the Iqamah." And they say that the meaning of Tashhad here is call the Adhan. An-Nasai recorded the Hadith with different chains (1054, 1137, 1314,1315). Whereas the wording narrated by At- Tirmidhi, and the author in Al-Kubra, mentions what the author mentioned in the chapter, the other cited versions that An-Nasai in this hook quoted do not. So it is as if he narrated the chain here for Hadith, indicating the same version that At-Tirmidhi narrated, and he himself in Al-Kubra, but he did not want to narrate the actual text here. Abu Dawud also narrated it with the order for the Adhan and Iqamah, through a different route of transmission (No. 861). And it is among the proofs used for the view that the Adhan and Iqamah are obligatory - since it has been ordered in the Hadith of the one who prayed incorrectly.
