Hazrat Moulana Hakeem Muhammad Akhtar Saheb (rahimahullah) mentioned the following:
Hazrat Moulana Ashraf Ali Thaanwi (rahimahullah) had prepared a kitaab named “Nashrut Teeb” in regard to the love of Rasulullah (sallallahu ‘alaihi wasallam). The entire kitaab revolves around love for Rasulullah (sallallahu ‘alaihi wasallam), and through reading this kitaab, one can gauge the deep love within the heart of the author for Rasulullah (sallallahu ‘alaihi wasallam).
During the time when Hazrat Moulana Ashraf Ali Thaanwi (rahimahullah) was engaged in the compilation of Nashrut Teeb, Thana Bowan (the town in which Hazrat Thaanwi [rahimahullah] resided) was afflicted by a plague. It was noticed that on the day when Hazrat Thaanwi (rahimahullah) wrote any portion of this kitaab, there would be no reports of people passing away due to the plague. However, on the day when Hazrat Thaanwi (rahimahullah) did not write any portion of the kitaab, reports of many people passing away would be heard. When this observation reached Hazrat Thaanwi (rahimahullah) via many people, he would not leave out writing this kitaab on any day. It was through the barakah (blessings) of writing about the great virtues and esteemed position of Rasulullah (sallalahu alaihi wasallam) during that time that Allah Ta‘ala caused the plague to come to an end.
After mentioning the above incident, Hazrat Moulana Hakeem Muhammad Akhtar Saheb (rahimahullah) concluded:
The recitation of abundant solah and salam upon Rasulullah (sallallahu ‘alaihi wasallam) is extremely beneficial in repelling calamities and disasters. Through reciting a single salawat, one’s rank is elevated by ten stages, ten good deeds are recorded in one’s account, and ten sins are forgiven. Additionally, through reciting abundant salawat, one is trying to fulfill the right of love which he owes to Rasulullah (sallallahu ‘alaihi wasallam). (Aadaab-e-Ishq-e-Rasul (sallallahu ‘alaihi wasallam) pg. 11)
