Sura Saad - Beautiful sound an

Sūra Sād (Arabic: سوره ص) is the thirty eighth sura of the Qur'an. It is a Makki sura in the twenty third juz'. The appellation of the sura as "Sad" is because of the occurrence of the disjointed letter, "sad", at the opening of the sura. Themes of the sura include the call to monotheism and sincerity by the Prophet (s), the obstinacy of polytheists against the truth, stories of some prophets, and what becomes of pious people and wrong-doers after the resurrection.

The occasion of the revelation of the sura (its first verses, indeed) was a conversation between unbelievers and the Prophet (s). The sura has a reference to a conversation between God and Iblis and the curse and outcast of Iblis as well. An effect of the recitation of this sura is said to be one's protection against minor and major sins.
