Quran 4:9 An-Nisa, ayah 9 of 176

وَلْيَخْشَ ٱلَّذِينَ لَوْ تَرَكُوا۟ مِنْ خَلْفِهِمْ ذُرِّيَّةً ضِعَـٰفًا خَافُوا۟ عَلَيْهِمْ فَلْيَتَّقُوا۟ ٱللَّهَ وَلْيَقُولُوا۟ قَوْلًا سَدِيدًا ۝٩

4:9 And let those fear (in their behaviour toward orphans) who if they left behind them weak offspring would be afraid for them. So let them mind their duty to Allah, and speak justly.
