Is supplicating to God for well-being from the phobia of losing relatives, and that none of the relatives die as long as the supplicant is alive, considered an act of transgression in supplication?

We advise this man to consult trustworthy doctors. He should know that calamities are inevitable in this worldly life, and he must accustom himself to patience, seeking Allah's help and asking Him for patience during affliction and gratitude during prosperity. He should entrust his affairs to Allah, knowing that Allah's decree is always good, and that every soul will receive its full provision and its appointed term. His supplication that he not lose any of his relatives during his lifetime is not considered an transgression in supplication.
