So true.I found this out when my dad passed away and my mother went to live w/my evil sister! Always made sure I said "I LOVE YOU" to my parents and was always there for them no matter what!I do not have any regrets, but we NEVER know when it will be the last time we see loved ones!!
When sick recite this supplication (dua): "O Lord of the people, remove this pain and cure it, You are the one who cures and there is no one besides You who can cure, grant such a cure that no illness remains"
Narrated `Abdullah bin Mas'ud: Allah's Messenger (ﷺ) said, "Do not wish to be like anyone, except in two cases: (1) A man whom Allah has given wealth and he spends it righteously. (2) A man whom Allah has given wisdom (knowledge of the Qur'an and the Hadith) and he acts according to it and teaches it to others."
