سورة قريش

Imam Baqir and Imam Sadiq (peace be upon them): أَ لَمْ تَرَ کَیْفَ [Have you not seen how] and لِإِیلَافِ [For the accustoming of] are both one surah.

Imam Sadiq (peace be upon him): One may not combine two surahs in a single rak'ah, except al-Duha and al-Inshirah, and Surah al-Fil and Quraysh.

Imam Sadiq (peace be upon him): Whoever recites Surah لِإِیلَافِ قُرَیْشٍ [For the security of Quraysh] often, Allah on the Day of Resurrection will raise him mounted on one of the mounts of Paradise, until on that day he sits at the tables of light.

The Messenger of Allah (peace be upon him and his family): Whoever recites this surah, Allah gives him the reward of one who performs tawaf around the Kaaba and observes i'tikaf in Masjid al-Haram; and when it is recited over food that is feared, it becomes a healing for that food, so that it will never harm the one who eats it in any way.

The Messenger of Allah (peace be upon him and his family): Whoever recites this surah over food will see no harm from it.

Imam Sadiq (peace be upon him): When this surah is recited over food that is feared, it becomes a healing for every ailment; and when you recite it over water and then that water is sprinkled on someone whose heart has fallen into illness and he does not know its cause, Allah removes that illness from him.
