Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned:
The Muslim Ummah gaining victory and success is not subject to the Muslims being few or many in number. Rather, victory is based on something else entirely. True victory for the Muslims is to make their sole priority in life to engage in the efforts of Deen and such work that will be pleasing to Allah Ta‘ala. If they gain success against the enemy, they should express gratitude to Allah Ta‘ala, and if they are not (apparently) successful then they should exercise patience. In reality, a believer is never unsuccessful, even though it may seem as if he did not succeed against the enemy. The reason for a believer always being successful is that he is always earning the reward of the Hereafter, which afterall is the objective and goal of every believer. (Malfoozaat Hakeemul Ummat 7/236)
