This excerpt is taken from the book of Sheikh Abi Abdul Saboor Abdul Ghafoor Damni Fazail al-Jihad.
عن أبى سعيد الخدري أن رسول الله صلى الله عليه وسلم قال يا أبا سعيد من رضي بالله ربا وبالإسلام دينا وبمحمد نبيا وجبت له الجنة، فعجب لها أبو سعيد فقال أعدها على يا رسول الله! ففعل ثم قال وأخرى يرفع بها العبد مائة درجة فى الجنة ما بين كل درجتين كما بين السماء والأرض قال وما هي يا رسول الله؟ قال الجهاد فى سبيل الله الجهاد فى سبيل الله.
"Abu Saeed Khudri (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) said: 'Whoever is pleased with Allah as his Lord, Islam as his religion, and Muhammad (peace be upon him) as his Prophet, Paradise becomes obligatory for him.' Abu Saeed (may Allah be pleased with him) was pleased with this and said: 'O Messenger of Allah! Please repeat this statement.' The Prophet (peace be upon him) repeated it, then said: 'There is another deed by which a servant will be granted one hundred degrees in Paradise, each degree being as far apart from the next as the distance between the heaven and the earth.' Abu Saeed (may Allah be pleased with him) asked: 'O Messenger of Allah! What is that?' The Prophet (peace be upon him) said: 'Jihad in the way of Allah, jihad in the way of Allah.'"
