Are there specific supplications to calm one's thoughts and get rid of fears of losing family members after hearing news of relatives' and friends' illnesses?

To calm a person who is afraid of the future: She should supplicate with words that remove her terror, fear, and anxiety, and ask Allah for well-being for herself and her family, such as: "O Allah, conceal my faults and calm my fears," and "O Allah, I ask You for pardon and well-being in my religion, my worldly affairs, my family, and my wealth." She should also frequently repeat: "Allah is sufficient for me; there is no god but He. In Him I put my trust, and He is the Lord of the Mighty Throne" seven times in the morning and in the evening. And remind her that everything is predetermined and nothing befalls the servants except what Allah has decreed for them.
