Faisal Award winner Abul Hasan Ali Nadvi R.A.writes
It was an ache that it distressed him all the time; he couldn't eat, he couldn't sleep. was a worry that had engulfed all other worries; it was a topic, the explanation and elucidation of which took up all energies of his tongue and pen to the extent that writing on any other subject was a trial for him.
He had written to Shaykhul Hadith Maulana Zakarya (rahimuhullah),
"My heartfelt desire is that at least my brain, thought, time, and energy should be limited to nothing but this work.
" He used to say, "How can any other occupation be lawful for me when I see that the soul of Rasulullah (sallallahu 'alaihe wasallam) is distressed (because of the weakness of the Muslims' faith and the supremacy of kufr)."
He did not attend gatherings where there was little chance of putting forward his message; he disliked going for the sake of an obligation only.
He used to say, "If you go to a place, go with your message and put it forward, keep your invitation above anything."
His speech in a wedding ceremony
Once in Delhi, he had to perforce attend a wedding ceremony of an acquaintance. He addressed the gathering at the wedding thus, "Today is the happiest of days for you when even the lowliest is pleased; it is not done to displease even the sweeperess………
Do you have any concern of pleasing Rasulullah (sallallahu 'alaihe wasallam)?" then he explained that the endeavour to revive the deen brought by Rasulullah (sallallahu 'alaihe wasallam) was the greatest way to please him (sallallahu 'alaihe wasallam).
This fine references are of the Revivalist of the Tablighi Jama'at, Maulana Muhammad Ilyas Noorullah marqadahu,
who adored calling to the Faith to such extent that all other sensory pleasures and opinions were dimmed before them; this spiritual pleasure had become sensory and natural for him.
