وَعَنْ أَبِي هُرَيْرَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: " قَالَ اللَّهُ تَعَالَى: وَمَنْ أَظْلَمُ مِمَّنْ ذَهَبَ بِخلق كخلقي فلْيخلقوا ذَرَّةً أَوْ لِيَخْلُقُوا حَبَّةً أَوْ شَعِيرَةً "

Abu Huraira told of hearing God’s messenger state that God most high says, “Who is more in the wrong than he who sets about creating things like what I have created ? Well, let such people create an atom, let them create a grain, or a grain of barley.” (Bukhari and Muslim).
