Al-Baqarah 2:260 واذ قال ابراهيم رب ارني كيف تحيي الموتى قال اولم تومن قال بلى ولاكن ليطمين قلبي قال فخذ اربعة من الطير فصرهن اليك ثم اجعل على كل جبل منهن جزءا ثم ادعهن ياتينك سعيا واعلم ان الله عزيز حكيم ٢٦٠

And when Abraham said (unto his Lord): My Lord! Show me how Thou givest life to the dead, He said: Dost thou not believe? Abraham said: Yea, but (I ask) in order that my heart may be at ease. (His Lord) said: Take four of the birds and cause them to incline unto thee, then place a part of them on each hill, then call them, they will come to thee in haste, and know that Allah is Mighty, Wise.
