[Machine] I saw Bilal giving the adhan, and he had placed his fingers in his ears while he was bending his head in his ears, right and left.  

رَأَيْتُ بِلَالًا يُؤَذِّنُ وَقَدْ جَعَلَ أُصْبُعَيْهِ فِي أُذُنَيْهِ وَهُوَ يَلْتَوِي فِي أَذَانِهِ يَمِينًا وَشِمَالًا  

[Machine] That the Messenger of Allah ﷺ ordered Bilal to put his fingers in his ears, and his stay was solitary, as he performed the prayer once.  

أَنَّ رَسُولَ اللهِ ﷺ أَمَرَ بِلَالًا أَنْ يُدْخِلَ أُصْبُعَيْهِ فِي أُذُنَيْهِ وَكَانَتْ إِقَامَتُهُ مُفْرَدَةً قَدْ قَامَتِ الصَّلَاةُ مَرَّةً وَاحِدَةً  

[Machine] That the Messenger of Allah ﷺ said to him, "When you give the call to prayer, place your index fingers in your ears, as it raises your voice."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَهُ إِذَا أَذَّنْتَ فَاجْعَلْ أُصْبَعَيْكَ فِي أُذُنَيْكَ فَإِنَّهُ أَرْفَعُ لِصَوْتِكَ  

[Machine] He said that the Prophet ﷺ commanded Bilal to call the Adhan, so he placed his fingers in his ears. The Prophet ﷺ looked at him but did not object to it. Since that day, this practice became Sunnah. It has been narrated from Ibn Sirin that Bilal used to place his fingers in his ears during some of his Adhans or Iqamahs.  

أَنَّهُ قَالَ أَمَرَ رَسُولُ اللهِ ﷺ بِلَالًا أَنْ يُؤَذِّنَ فَجَعَلَ إِصْبَعَيْهِ فِي أُذُنَيْهِ وَرَسُولُ اللهِ ﷺ يَنْظُرُ إِلَيْهِ فَلَمْ يُنْكِرْ ذَلِكَ فَمَضَتِ السُّنَّةُ مِنْ يَوْمَئِذٍ وَرُوِّينَا عَنِ ابْنِ سِيرِينَ أَنَّ بِلَالًا جَعَلَ أُصْبُعَيْهِ فِي أُذُنَيْهِ فِي بَعْضِ أَذَانِهِ أَوْ فِي إِقَامَتِهِ
