A wasteful and extravagant attitude in using properties is an act prohibited in Islam. There are several verses in the Quran prohibiting this wasteful and extravagant attitude. Verses about tabzir are sometimes not well understood by the public and students, such as those at the Selangor Islamic University College (KUIS) in Malaysia. It is undeniable that the level of understanding and practice of the tabzir verses can affect their daily life behavior. The objectives of this paper were to review tabzir meaning in the Al-Qur'an and to examine the level of understanding and practice on tabzir verses of Kolej Universiti Islam Antar Bangsa Selangor (KUIS) students. In addition, this study also aimed to closely examine the practical implications of the understanding and practice of the tabzir verses on student behavior in their lives
