Surah An-Nisa, ayah 9

4:9

وَلۡيَخۡشَ ٱلَّذِينَ لَوۡ تَرَكُواْ مِنۡ خَلۡفِهِمۡ ذُرِّيَّةٗ ضِعَٰفًا خَافُواْ عَلَيۡهِمۡ فَلۡيَتَّقُواْ ٱللَّهَ وَلۡيَقُولُواْ قَوۡلٗا سَدِيدًا ٩

Walyakhshal-ladhīna law tarakū min khalfihim dhurriyyatan di'āfan khāfū 'alayhim falyattaqullāha walyaqūlū qawlan sadīdā

And let those [executors and guardians] fear [injustice] as if they [themselves] had left weak offspring behind and feared for them. So let them fear Allāh and speak words of appropriate justice.
