يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَيَبْلُوَنَّكُمُ ٱللَّهُ بِشَىْءٍۢ مِّنَ ٱلصَّيْدِ تَنَالُهُۥٓ أَيْدِيكُمْ وَرِمَاحُكُمْ لِيَعْلَمَ ٱللَّهُ مَن يَخَافُهُۥ بِٱلْغَيْبِ ۚ فَمَنِ ٱعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُۥ عَذَابٌ أَلِيمٌۭ
O ye who believe! Allah will surely try you somewhat (in the matter) of the game which ye take with your hands and your spears, that Allah may know him who feareth Him in secret. Whoso transgresseth after this, for him there is a painful doom.

Chapter: What is the proper period for reciting the whole Qur'an
Narrated `Abdullah bin `Amr:
Allah's Messenger (ﷺ) said to me, "Recite the whole Qur'an in one month's time." I said, "But I have power (to do more than that)." Allah's Messenger (ﷺ) said, "Then finish the recitation of the Qur'an in seven days, and do not finish it in less than this period."
