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 [mention] when Abraham said, "My Lord, show me how You give life to the dead." [Allāh] said, "Have you not believed?" He said, "Yes, but [I ask] only that my heart may be satisfied." [Allāh] said, "Take four birds and commit them to yourself.¹ Then [after slaughtering them] put on each hill a portion of them; then call them - they will come [flying] to you in haste. And know that Allāh is Exalted in Might and Wise."
