So We have made it easy to understand in your tongue, as a summary of the surah. Its meaning is: remind them with the clear Book. So We have made it easy means: We have made it simple, as We revealed it in Arabic in your language, intending for your people to understand it and remember. So wait for what will happen to them. Indeed, they are waiting for what will happen to you, lurking in ambush.

From the Messenger of Allah, blessings and peace be upon him: "Whoever recites Surah Ham Al-Dukhan at night, seventy thousand angels will seek forgiveness for him in the morning." [Narrated by Al-Tirmidhi, Ibn Adi, Al-Shabi, and Al-Bayhaqi in Al-Shu'ab from the narration of Umar bin Khutham from Yahya bin Abi Kathir from Abu Salamah from Abu Hurairah, and he said: It is strange, and Umar is weak. Muhammad said: It is a rejected hadith. I say: It is similar to the one before it.] And from him, peace be upon him: "Whoever recites Ham in which the smoke is mentioned on a Friday night, he will be forgiven in the morning." [Narrated by Al-Tirmidhi, Abu Ya'la, Ibn Al-Sunni in Al-Yawm wa Al-Laylah, and Al-Bayhaqi in Al-Shu'ab, and it was uniquely narrated by Abu Al-Muqdam. And it is weak. And from Al-Hasan from Abu Hurairah, and Al-Tirmidhi said: Abu Al-Muqdam is weak, and Al-Hasan did not hear from Abu Hurairah.]}
