Mishkat al-Masabih 9 Supplications كتاب الدعوات 90

وَعَنْ يُسَيْرَةَ رَضِيَ اللَّهُ عَنْهَا وَكَانَتْ مِنَ الْمُهَاجِرَاتِ قَالَتْ: قَالَ لَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «عَلَيْكُنَّ بِالتَّسْبِيحِ وَالتَّهْلِيلِ وَالتَّقْدِيسِ واعقِدْنَ بالأناملِ فإِنهنَّ مسؤولات مُسْتَنْطَقَاتٌ وَلَا تَغْفُلْنَ فَتَنْسَيْنَ الرَّحْمَةَ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُد

Busaira, who was one of the women emigrants, told of God’s messenger saying to them, “Apply yourselves to glorifying God, saying there is no god but He, and declaring His holiness; and count them on your fingers, for they [i.e. the fingers] will be questioned and asked to speak; and do not be negligent and so be deprived of mercy.” Tirmidhi and Abu Dawud transmitted it.
