Assalamu alaikum warahmatullahi wabarakatuhu
I would like to present another good dua that would protect us from many of our shortcomings, weaknesses, etc. I especially specify this dua as there is a protection from old age related weaknesses and diseases.
Anas (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) used to supplicate: “Allahumma inni a’udhu bika minal-ajzi wal- kasali, wal-jubni wal-harami, wal-bukhli, wa a’udhu bika min 'adhabil- qabri, wa a’udhu bika min fitnatil-mahya wal-mamat [O Allah! I seek refuge in You from helplessness (to do good), indolence, cowardice, senility, and miserliness; and I seek Your Protection against the torment of the grave and the trials of life and death] .” Another narration adds: “wa dala’id-daini wa ghalabatir-rijal (And from the burden of indebtedness and the tyranny of men).”
