This prayer is taken from Sayyidi Habib Umar bin Hafiz’s collection of prayers using Allah’s beautiful names in which he calls upon Allah by His beautiful names and then asks Him to bestow prayers upon His Beloved by those names. Finally, he asks Allah for a portion of those attributes which belong to Allah and which He has bestowed upon His Messenger ﷺ.
اللَّهُمَّ يا اللهُ يا مَتِينُ صَلِّ على عَبْدِكَ و حَبِيبِكَ سَيِّدِنا مُحَمَّدٍ النَّبِيِّ صَاحِبِ الدِّينِ المتَيِن و على آلِهِ و صَحْبِهِ و سَلِّمْ تَسْلِيماً وارْزُقْنِي الاعْتِصَامَ بِالحَبْلِ المَتِينِ واجْعَلْ لي في وُصْلَتِكَ و وُصْلَتِهِ حَبْلاً مَتِيناً
Allāhumma yā Allāhu yā Matīnu ṣalli ‘alā ‘abdika wa ḥabībika sayyidinā Muḥammad an-Nabī ṣāḥibi’ddīn’l-matīn wa ‘alā ālihi wa ṣaḥbihi wa sallim taslīman wa’rzuqnī’l-‘itiṣāma bi’l-ḥabli’l-matīn wa’j`al lī fī wuṣlatika wa wuṣlatihi ḥablan matīnā
O Allah, O Most Firm, bestow abundant prayers and peace upon Your slave and beloved, our Master Muhammad, the leader of the firmest religion, and upon his Family and Companions, and allow me to hold fast to the Firm Rope and make my connection to You and him the firmest of ropes.
