Hadith 151B6

قَالَ يَحْيَى: وَسُئِلَ مَالِك ، عَنْ مُؤَذِّنٍ أَذَّنَ لِقَوْمٍ ثُمَّ تَنَفَّلَ ، فَأَرَادُوا أَنْ يُصَلُّوا بِإِقَامَةِ غَيْرِهِ؟ فَقَالَ: لَا بَأْسَ بِذَلِكَ إِقَامَتُهُ وَإِقَامَةُ غَيْرِهِ سَوَاءٌ
Imam Malik (may Allah have mercy on him) was asked that if a muezzin gave the call to prayer, then started offering voluntary prayers, and now people intend to establish the congregation with the takbir of another person, what is the ruling? Imam Malik (may Allah have mercy on him) replied that there is nothing objectionable in this, whether the muezzin says the takbir or another person says it, both are the same.
