Sura al-Nisāʾ 4:9

وَلْيَخْشَ ٱلَّذِينَ لَوْ تَرَكُوا۟ مِنْ خَلْفِهِمْ ذُرِّيَّةً ضِعَٰفًا خَافُوا۟ عَلَيْهِمْ فَلْيَتَّقُوا۟ ٱللَّـهَ وَلْيَقُولُوا۟ قَوْلًا سَدِيدًا

wa-l-yakhsha lladhīna law tarakū min khalfihim dhurriyyatan ḍiʿāfan khāfū ʿalayhim fa-l-yattaqū allāha wa-l-yaqūlū qawlan sadīdan

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).
