Translation of "Afflicted" in Arabic

I knew that brains afflicted with MS, over time, shrank.

كنت أعرف أن العقول المصابة بمرض التصلب المتعدد مع االوقت، تتقلص.

Khadija said "Never! By Allah, Allah will never disgrace you. You keep good relations with your kith and kin, help the poor and the destitute, serve your guests generously and assist the deserving calamity-afflicted ones.

قَالَتْ خَدِيجَةُ: كَلَّا وَاللَّهِ مَا يُخْزِيكَ اللَّهُ أَبَدًا إِنَّكَ لَتَصِلُ الرَّحِمَ وَتَحْمِلُ الْكَلَّ وَتَكْسِبُ الْمَعْدُومَ وَتَقْرِي الضَّيْفَ وَتُعِينُ عَلَى نَوَائِبِ الْحَقِّ.
