What are the virtues of Alif Laam Meem Suras ?

[Mahmud200]

Assalaamu Alaikum.
The Holy Quran has several Suras starting with the letters Alif Lam Mim. Does anyone know the Fazilats of these Suras?

[True Life]

There are many, for example Shaytan flees from the house in which Surah Baqarah is recited and Rasulullah according to a narration would not go to sleep before reciting Surah Sajdah. But I doubt these benefits are on the sole basis of them beginning with Alif-Lam-Mim, because other Surahs that don't have as we know magnificant virtues, too. Other than that for reciting just Alif-Lam-Mim itself you'll be rewarded by 30 hasanat (currency of Akhirah).
