An-Nisa' - 4:9

وَلْيَخْشَ الَّذِينَ لَوْ تَرَكُواْ مِنْ خَلْفِهِمْ ذُرِّيَّةً ضِعَافًا خَافُواْ عَلَيْهِمْ فَلْيَتَّقُوا اللّهَ وَلْيَقُولُواْ قَوْلاً سَدِيدًا
[4:9]
And let those fear who, should they leave behind them weakly offspring, would fear on their account, so let them be careful of (their duty to) Allah, and let them speak right words.
Let those (disposing of an estate) have the same fear in their minds as they would have for their own if they had left a helpless family behind: Let them fear Allah, and speak words of appropriate (comfort).
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.
