ٱللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلْأَرْحَامُ وَمَا تَزْدَادُ ۖ وَكُلُّ شَىْءٍ عِندَهُۥ بِمِقْدَارٍ
Allah knoweth that which every female beareth and that which the wombs absorb and that which they grow. And everything with Him is measured.

Chapter: The story of Daus and Tufail bin ‘Amr Ad-Dausi
Narrated Abu Huraira:
When I came to the Prophet (ﷺ) said on my way, "O what a long tedious tiresome night; nevertheless, it has rescued me from the place of Heathenism." A slave of mine ran away on the way. When I reached the Prophet (ﷺ) I gave him the oath of allegiance (for Islam), and while I was sitting with him, suddenly the slave appeared. The Prophet (ﷺ) said to me. "O Abu Huraira! Here is your slave," I said, "He (i.e. the slave) is (free) for Allah's Sake," and manumitted him.
