Al 'Imran, 165 Ayah
3:165
أَوَلَمَّآ أَصَٰبَتۡكُم مُّصِيبَةٞ قَدۡ أَصَبۡتُم مِّثۡلَيۡهَا قُلۡتُمۡ أَنَّىٰ هَٰذَاۖ قُلۡ هُوَ مِنۡ عِندِ أَنفُسِكُمۡۗ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَيۡءٖ قَدِيرٞ ١٦٥
'Awalammā 'Aşābatkum Muşībatun Qad 'Aşabtum Mithlayhā Qultum 'Anná Hādhā ۖ Qul Huwa Min `Indi 'Anfusikum ۗ 'Inna Al-Laha `Alá Kulli Shay'in Qadīrun
Why [is it that] when a [single] disaster struck you [on the day of Uhud], although you had struck [the enemy in the battle of Badr] with one twice as great, you said, "From where is this?" Say, "It is from yourselves." Indeed, Allah is over all things competent.
