It is written in Unity of The Ummah By Mufti Muhammad Shafi Usmani
When Sheikhul Hind Moulana Mahmudul Hasan rahimahullah was released from the prison of Malta after spending four years of incarceration, he returned to Darul Ulum Deoband and mentioned something very important to a gathering of Ulama.
Those people who knew Sheikhul Hind rahimahullah also know that his imprisonment was not like the imprisonment of normal political leaders. During the war of independence, all his movements were only for the pleasure of Allah - in order that the Ummah be reformed and successful. While he was a traveller in a hopeless condition, at the time of his arrest, the sentence that was on his lips gives some indication of his resoluteness and his aim. He said,
"All praises are due to Allah that I have been arrested due to a problem and not due to sin."
In the solitude of the jail, when some of his companions saw him in grief, they attempted to console him. He said, "What grief can there be for this problem which will one day terminate. I am grieving whether this hardship and toil will be accepted by Allah if or not."
One night, after his release, he addressed the Ulama after Isha in Darul Ulum and said, "I have learnt two lessons in Malta." On hearing this, everyone shot to attention and wondered what this teacher of all teachers who taught Ulama for eighty years, learnt in the final phase of his life. He said, "I pondered in the solitude of the prison why the Muslims in the whole world are being destroyed with regard to both, their religious and worldly lives, I concluded that there are two causes for this. One is their discarding the Qur'an and secondly, their mutual differences and disputes. Accordingly, I have come with a firm intention from there to spend the rest of my life in spreading the Qur'an by making its words and meanings common. Madrasahs should be established to teach the children Qur'an in every village. The adults should be educated with the meanings of the Qur'an in the form of Qur'anic lessons. They should be encouraged to practise on the Qur'anic teachings. Under no circumstances must the mutual disputes and quarrels of the Muslims be tolerated."
After taking the pulse of the Ummah and diagnosing their diseases, he continuously spent the remaining days of his life in administering the cure in spite of his ill health, weakness and preoccupations. He himself started lessons of the Qur'an in which all the Ulama of the city and great luminaries like Moulana Husain Ahmad Madam rahimahullah and Moulana Shabbir Ahmad Uthmam rahimahullah participated. The general public and I myself had the honour of participating. But after this incident, only a few days of Hadrat's rahimahullah life remained.
Today also, the problems the Muslims are facing have the same two causes if one has to examine them with insight:
1. discarding the Qur'an and
2. mutual in-fighting.
If one ponders, this in-fighting is also caused by abandoning the Qur'an. If we had practised even a little on the Qur'an, our disputes would not have reached this stage.
