Surat Az-Zumar (The Troops) - سورة الزمر

: Say (O Muhammad SAW) "Allah Alone I worship by doing religious deeds sincerely for His sake only and not to show-off, and not to set up rivals with Him in worship."

: So worship what you like besides Him. Say (O Muhammad SAW): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!"

: They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!"

: Those who avoid At-Taghut (false deities) by not worshipping them and turn to Allah in repentance, for them are glad tidings; so announce the good news to My slaves,

: Those who listen to the Word [good advice La ilaha ill-Allah (none has the right to be worshipped but Allah) and Islamic Monotheism, etc.] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut, etc.) those are (the ones) whom Allah has guided and those are men of understanding (like Zaid bin 'Amr bin Nufail, Salman Al-Farisi and Abu Dhar Al-Ghifari). [Tafsir Al-Qurtubi, Vol. 12, P. 244]

: Is, then one against whom the Word of punishment justified (equal to the one who avoids evil). Will you (O Muhammad SAW) rescue him who is in the Fire?

: But those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms; one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (His) Promise.
