Bilal was commanded (by the Holy Prophet) to repeat the phrases twice in Adhan, and once in lqama.  

أَنْ يَشْفَعَ الأَذَانَ وَيُوتِرَ الإِقَامَةَ  

"The Messenger of Allah ﷺ commanded Bilal to say the phrases of the Adhan twice and the phrases of the Iqamah once."  

إِنَّ رَسُولَ اللَّهِ ﷺ أَمَرَ بِلاَلاً أَنْ يَشْفَعَ الأَذَانَ وَأَنْ يُوتِرَ الإِقَامَةَ  

"Bilal was ordered to make the phrases of the Adhan even, and the phrases of the Iqamah odd."  

أَنْ يَشْفَعَ الأَذَانَ وَيُوتِرَ الإِقَامَةَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ  

"They looked for something by means of which they could call out informing of (the time of) the prayer. Then Bilal was commanded to say the phrases of the Adhan twice and the phrases of the Iqamah once."  

الْتَمَسُوا شَيْئًا يُؤْذِنُونَ بِهِ عِلْمًا لِلصَّلاَةِ فَأُمِرَ بِلاَلٌ أَنْ يَشْفَعَ الأَذَانَ وَيُوتِرَ الإِقَامَةَ  

"Bilal was commanded to say the phrases of the Adhan twice and the phrases of the Iqamah once."  

أَنْ يَشْفَعَ الأَذَانَ وَيُوتِرَ الإِقَامَةَ  

"Bilal was commanded to say the phrases of the Adhan twice and the phrases of the Iqamah once." (Using translation from Ibn Mājah 730)  

«أُمِرَ بِلَالٌ أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ»  

Anas reported; Bilal was commanded to pronounce Adhan in double pairs and IQAMAH in single pairs. Hammam added in his version; “except IQAMAH”. (Using translation from Abū Dāʾūd 508)   

«أُمِرَ بِلَالٌ أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ إِلَّا الْإِقَامَةَ»  

"The Messenger of Allah ﷺ commanded Bilal to say the phrases of the Adhan twice and the phrases of the Iqamah once." (Using translation from Nasāʾī 627)  

أَنَّ رَسُولَ اللَّهِ ﷺ «أَمَرَ بِلَالًا أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ»  

[Machine] The Messenger of Allah ﷺ ordered Bilal to give the call to prayer and perform the qiyam (night prayer). The two shaykhs did not mention this context, but it is correct according to their condition.  

أَنَّ رَسُولَ اللَّهِ ﷺ «أَمَرَ بِلَالًا أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ» «وَالشَّيْخَانِ لَمْ يُخَرِّجَا بِهَذِهِ السِّيَاقَةِ وَهُوَ صَحِيحٌ عَلَى شَرْطِهِمَا»  

"Bilal was commanded to say the phrases of the Adhan twice and the phrases of the Iqamah once." (Using translation from Ibn Mājah 730)

أَمَرَ رَسُولُ اللهِ ﷺ بِلَالًا أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ  

"عَنْ أَنَسٍ أَنَّ النَّبِي ﷺ أمَرَ بِلاَلًا: أنْ يَشْفَعَ الأذَانَ وَيُوتِرَ الإِقَامَةَ".

"عَنْ أنَس قَالَ: أمِرَ بِلاَل أنْ يَشْفَعَ الأذَانَ، وَيُوتِر الإِقَامَة".  

"عَنِ ابْنِ عُمَرَ أنَّ النَّبِىَّ ﷺ أمَرَ بِلاَلًا أنْ يَشْفَعَ الأذَانَ، وَيُوتِرَ الإِقَامَةَ".
