Is the Hadith, "Whoever says 'Subhanallahi wa bihamdihi, Subhanallahil Azeem' (Glorified is Allah and praised is He, Glorified is Allah, the Most High) one hundred times, all his sins will be forgiven," authentic? Does it include major sins? Does it suffice for the prayer of repentance if recited daily? Is it enough to say only "Subhanallahi wa bihamdihi"? Is there a preferred time for reciting this dhikr, or is it permissible at any time?

The virtues of the dhikr (remembrance of Allah) "Subhanallahi wa bihamdihi, Subhanallahil-Azim" (Glory be to Allah and praise be to Him, Glory be to Allah, the Most Magnificent) and "Subhanallahi wa bihamdihi" (Glory be to Allah and praise be to Him) are explained. "Subhanallahi wa bihamdihi, Subhanallahil-Azim" are two phrases light on the tongue, heavy on the scale, and beloved to the Most Merciful. As for "Subhanallahi wa bihamdihi," whoever says it one hundred times in a day, his sins will be forgiven even if they are like the foam of the sea. And whoever says it one hundred times in the morning and one hundred times in the evening, no one will come on the Day of Resurrection with anything better than what he brought, except for one who said the same as he did or added more. Major sins are not expiated except by sincere repentance, whereas minor sins can be expiated by good deeds and dhikr, with the understanding that persistence in minor sins may turn them into major sins. It is permissible to restrict oneself to "Subhanallahi wa bihamdihi" or "Subhanallahi wa bihamdihi, Subhanallahil-Azim," and it is better to alternate between them. The best times to say "Subhanallahi wa bihamdihi" one hundred times are after Fajr prayer or before Maghrib prayer.
