Do Dua Surah Ash-Shura 49-50
To Allah belongs the kingdom of the heavens and the earth. He creates what He wills. He grants females to whom He wills, and grants males to whom He wills. (49) Or He combines for them couples, both males and females, and makes whom He wills barren. Surely, He is All-Knowing, Very-Powerful. (50)
