Al-Habib Umar bin Hafiz encourages making lots of this (salutations) formula in the month of Rabi’ul Awwal 1437H:

اَللَّهُمَّ يَا رَبَّ سَيِّدِنَا مُحَمَّدٍ وَآلِ سَيِّدِنَا مُحَمَّدٍ صَلِّ وَسَلِّمْ عَلَى سَيِّدِنَا مُحَمَّدٍ وَعَلَى آلِ سَيِّدِنَا مُحَمَّدٍ، وَأَذْهِبْ حُزْنَ قَلْبِيْ فِيْ الدُّنْيَا وَالْآخِرَةِ، وَأَجْرِ يَا رَبِّ لُطْفَكَ الْخَفِيَّ فِيْ أُمُوْرِنَا وَأُمُوْرِ الْمُسْلِمِيْنَ

Transliteration: ALLAHumma ya Rabba Sayyidina Muhammad wa Aali Sayyidina Muhammad, Solli wa Sallim ‘ala Sayyidina Muhammad wa ‘ala Aali Sayyidina Muhammad, wa azhib huzna qolbi fid dunya wal akhirah, wa ajri ya Rabbi luthfakal khafiyya fi umurina wa umuril Muslimin.

Meaning: O Allah, Lord of our Master Muhammad ﷺ and the Family of our Master Muhammad ﷺ, send blessings and peace upon our Master Muhammad ﷺ and the Family of our Master Muhammad ﷺ, and remove the sadness of my heart in this World and the Hereafter, and let flow Your Hidden Gentleness in our affairs, and in the affairs of the Muslims, O Lord.

The minimum of it (recitation in Rabi’ul Awwal): 10,000 times.
