The Prophet ﷺ said: “Whoever says in the morning and in the evening ‘Glory is to Allah and with His Praise (Subḥān Allāh, wa biḥamdih)’ a hundred times, none shall bring better than him on the Day of Judgment except one who did the same as him, or increased upon it.”
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ قَالَ حِينَ يُصْبِحُ وَحِينَ يُمْسِي سُبْحَانَ اللَّهِ وَبِحَمْدِهِ مِائَةَ مَرَّةٍ لَمْ يَأْتِ أَحَدٌ يَوْمَ الْقِيَامَةِ بِأَفْضَلَ مِمَّا جَاءَ بِهِ إِلاَّ أَحَدٌ قَالَ مِثْلَ مَا قَالَ أَوْ زَادَ عَلَيْهِ
