Hadith 102102 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: مَن قَرَأَ سُورَة أَربَعَ مَرَّاتٍ، كانَ كَمَنْ قَرَأَ الْقُرْآنَ كُلَّهُ.
31-102 According to the same documentation, God’s Prophet (S) said, “Whoever recites the Chapter (of the Qur’an) starting with ‘When the earth is shaken to her (utmost) convulsion…’ four times, it is as if he has recited the whole Qur’an.”
