There is no god save Thou. Be Thou glorified! Verily, I have been a wrongdoer,
My Lord! I am needy of whatever good Thou sends down for me.
My Lord! Leave me not alone (childless), though Thou art the best of inheritors

O my Allah, the honour of being Your servant is sufficient. 
I am proud of the fact that You are my Lord. 
You are just as I want, so make me just as You like me to be. 
الهي كفى بي عزّا أن أكون لك عبدا ،
 وكفى بي فخرا أن تكون لي ربّا
... أنت كما أُحبُّ ،  فاجعلني كما تحبُّ
اللهم عجل لوليك الفرج يا الله
(SAWW): How wonderful is the case of a believer; there is good for him in everything and this applies only to a believer.
If prosperity attends him, he expresses gratitude to Allah and that is good for him;
and if adversity befalls him, he endures it patiently and that is better for him".
Amir al-Mu'minin Imām 'Alī ibn Abī Tālib (A.S) said: 'Even if Allāh(SWT)
had not fixed punishments and threats for acts of disobedience to Him,
we would still be obliged not to disobey Him, simply by way of gratitude to Him for His bounties.
Imām Mūsā ibn Ja‘far al-Kāzim  (a.s.) said: “One who supplicates for believers,
the Almighty Allāh appoints an angel for each believer to supplicate for that person.
