Islam is a School. Deen is a Class. World is a Campus. We all are Students. Quran Pak is Syllabus. Zakat is our Investment. Ramadan is our Test. Prayer (Namaz) is our Practical. Hazrat Muhammad (ﷺ) is our Teacher. Allah Almighty is the Examiner and The Day Of judgement is the Date Of Result. So we have to get good marks.
