Narrated by:Maslamah bin `Amr said:
“`Umair bin Hani used to perform a thousand prostrations every day and recite a hundred thousand Tasbīḥs every day.”
حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ حَدَّثَنَا مَسْلَمَةُ بْنُ عَمْرٍو قَالَ كَانَ عُمَيْرُ بْنُ هَانِئٍ يُصَلِّي كُلَّ يَوْمٍ أَلْفَ سَجْدَةٍ وَيُسَبِّحُ مِائَةَ أَلْفِ تَسْبِيحَةٍ .
