Don't be Sad is a book I'm currently reading. There is a particular paragraph in this book which I have reproduced below to allow others to recite this as their Do'a/prayer and ask Allah swt to grant us a good life and success in the world and the hereafter. I write this doa/prayer in a clean sheet of paper and keep it in my handbag. This gives me a sense of security and feeling of protection from Allah. Try writing it down and you will know what I mean.
" There is none worthy of worship except Allah, the Ever-Forebearing, the Most Great. There is none worthy of worship except Allah, the Lord of the Tremendous Throne. There is none worthy of worship except Allah,the Lord of the Heavens, the Lord of the earth, and the Lord of the Noble Throne. O'Ever-Living, and O'One Who sustains and protects all that exists, there is none worthy of worship except You and by Your mercy do we seek Your aid."
O'Allah, Your mercy do I hope for; so do not leave to myself, not even for the blinking of an eye. and make well for me all of my affairs. There is none worthy except You."
" I seek forgiveness from Allah: none is worthy of worship except Him. He is the Ever-Living and the One ho sustains and protects all that exists, and I turn to Him in repentance."
" There is none worthy of worship except You, and how perfect You are: verily; I am among the wrongdoers."
" O' Allah, verily I am Your slave, the son of Your slaves; my forelock is in Your hand. Your order concerning me will be executed and just is Your judgement upon me. I ask You by all of Your names that You have named Yourself with, have revealed in Your book, have taught to one of Your creation, or is in Your knowledge only (from the matters of the unseen)-make Qu'ran the spring of my heart, the light of my chest, the remover of my sadness, and the purger of my anxiety."
"O' Allah, I seek refuge in you from anxiety and grief, from inability and laziness, from avarice and cowardice, from being engrossed by debt, and from being overpowered by men."
" Allah (Alone) is Sufficient for us, and He is the Best Disposer of affairs (for us)." Ameen
