O Allah: (please do) send blessings upon Muhammad and the Household of Muhammad, the tree of Prophethood; and the trustees of the (Divine) Mission; and the frequently visited by the angels; and the core of knowledge; and the Household of the Divine Revelation.

O Allah: (please do) send blessings upon Muhammad and the Family of Muhammad the sailing ships through the abysmal waves.

He who embarks on will be saved but he who abandons will be drowned.

He who precedes them will miss the Right Path and he misses them will lose, but he who adheres to them will win.

O Allah: (please do) send blessings upon Muhammad and the Household of Muhammad the impregnable shelter; and the succorers of the helpless, distressed ones; and the haven of the fugitives; and the asylum of those who seek refuge.

O Allah: (please do) send blessings upon Muhammad and the Household of Muhammad so much blessings that please them and settle all (our) duties towards Muhammad and the Household of Muhammad by Your might and power; O the Lord of the worlds.

O Allah: (please do) send blessings upon Muhammad and the Household of Muhammad the pure, the pious, the righteous whose rights have been made incumbent upon us by You and the obedience to whom has been deemed obligatory upon us by You and whose (divinely commissioned) leadership has been (also) deemed obligatory upon us by You.

O Allah: (please do) send blessings upon Muhammad and the Household of Muhammad; and fill in my heart with the obedience to You; and do not disgrace me by acts of disobedience to You; and grant me the feeling of sympathy towards those whom You have decided to straighten their sustenance by means of Your favours that You have decided to make expansive for me and by means of that with which You have covered me out of Your fairness; and make me live under Your shade.

This is the month of Your Prophet and the Master of Your Messengers. It is Sha`ban, which You have encompassed with Your mercy and pleasure, and on which the Messenger of Allah—peace and blessings be upon him and his Family—used to observe fasting painstakingly and used to spend it with acts of worship on all of its days and night on account of Your honouring and dignifying this month, up to his death.

O Allah: (please do) help us follow the example of him (i.e. the Holy Prophet as regards the honouring of this month) and help us attain nearness to him.

O Allah: (please do) decide him as my interceder (before You) whose intercession for me is acceptable and as my clear path toward You; and make me follow him until I meet You on the Resurrection Day enjoying Your pleasure with me and Your overlooking my sins and thus You will confer upon me with Your mercy and pleasure and allow me to reside in the Eternal Abode and the Place of the Righteous.
