“The Messenger of Allah ﷺ entered upon me and before me were four thousand date pits, I was making Tasbih with them. He said: ‘You have made Tasbih with these? Should I not teach you that which is more than what you have made Tasbih with?’ So I said: ‘Indeed, teach me.’ So he said: ‘Say: glory is to Allah according to the number of His creation (Subḥān Allāhi ʿadada khalqihi).’”
سَمِعْتُ صَفِيَّةَ تَقُولُ دَخَلَ عَلَىَّ رَسُولُ اللَّهِ ﷺ وَبَيْنَ يَدَىَّ أَرْبَعَةُ آلاَفِ نَوَاةٍ أُسَبِّحُ بِهَا فَقُلْتُ لَقَدْ سَبَّحْتُ بِهَذِهِ فَقَالَ أَلاَ أُعَلِّمُكِ بِأَكْثَرَ مِمَّا سَبَّحْتِ بِهِ فَقُلْتُ بَلَى عَلِّمْنِي فَقَالَ قُولِي سُبْحَانَ اللَّهِ عَدَدَ خَلْقِهِ
