Mishkat al-Masabih, 2313

‘Abdallah b. ‘Amr reported God’s messenger as saying that “Glory be to God” fills half the scale, “Praise be to God” fills it, and “There is no god but God” has no veil between it and God till it reaches Him. Tirmidhi transmitted it, saying this is a <i>gharib</i> tradition whose <i>isnad</i> is not strong.

وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «التَّسْبِيحُ نِصْفُ الْمِيزَانِ وَالْحَمْدُ لِلَّهِ يَمْلَؤُهُ وَلَا إِلَهَ إِلَّا اللَّهُ لَيْسَ لَهَا حِجَابٌ دُونَ اللَّهِ حَتَّى تَخْلُصَ إِلَيْهِ» . رَوَاهُ التِّرْمِذِيُّ. وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ وَلَيْسَ إِسْنَاده بِالْقَوِيّ
