Remembrance of Allah

The principle:	Abu Musa Ash`ari berichtet: The case of a person who remembers his Lord and of one who does not remember Him is like that of the living and the dead. (Al-Bukhāri) RS-1439 (1434)

subHāna-LLah 100 x	Sa`d bn Abi Waqqās related: Once we were sitting with the Holy Prophet ﷺ when he said: Could any of you have the strength to earn a thousand virtues in a day? One of the audience asked as to how one thousand good deeds be earned. He answered ﷺ: If one glorifies Allah (ie. recites subHāna-LLah), a hundred times he would be credited with a thousand good deeds or a thousand sins would be remitted. (Muslim) RS-1436 (1431)
	Other regular devotions:
lā ilāha ill-ALLAHu 1000 x	morning and evening, or as often as possible
astighfār 100 x	morning and evening, or 27x after S. Fajr for the believers (hadith)

100x ev. day	(Who says:) lā ilāha ill-ALLAHu, wahdahu lā shārik-ALLAHu lahu-l mulku wa lahu-l hamd, wa huwa `ala kulli shayin qadīr as the freeing of 10 slaves, 100 virues recorded, 100 vices blotted out, is a safeguard against Shaitan till evening... M-6508
