عَنْهُ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ وَهْبٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَآلِهِ مَنْ أَذَّنَ فِي مِصْرٍ مِنْ أَمْصَارِ اَلْمُسْلِمِينَ سَنَةً وَجَبَتْ لَهُ اَلْجَنَّةُ
From him, from Ya'qub ibn Yazid, from Ibn Abi Umayr, from Mu'awiyah ibn Wahb:
Abu Abdillah عليه السلام, peace be upon him, said: “The Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, said: "Whoever gives the Adhan in a city among the cities of the Muslims for one year, Paradise becomes obligatory for him."
