Sabr is an Arabic word that means "endurance," "perseverance," "patience," "restraint," and "resignation". It is one of the two parts of faith in Islam, the other being shukr (gratitude) . Sabr is a concept that conveys a very active, dynamic, and positive quality in Islam. It is the quality of surging forward, striving, and not slackening in our purpose to purify the soul. Sabr is required to fulfill the commands of Allah, to remain spiritually steadfast, and to keep doing good actions in the personal and collective domain, specifically when facing opposition or encountering problems, setbacks, or unexpected situations.

Sabr has different meanings in Islam, including:

• Endurance and perseverance: Sabr means to endure, bear, and resist pain, suffering, and difficulty, and to deal calmly with problems. It is the quality of being patient in the face of adversity and remaining steadfast in faith.

• Restraint: Sabr means restraint, which is required for refraining from what Allah has prohibited and from all kinds of disobedience and sin.

• Resignation: Sabr means resignation or acceptance, which is required when facing a difficult situation that cannot be changed.

Sabr is associated with acts of worship and obedience, even if they are hard on the heart and the body, and avoiding what Allah dislikes, even if it is desired. Sabr is also related to the concept of jihad, where it is translated as "endurance" or "tenacity".

According to the Quran, those who possess sabr to a certain extent are called sabirun. The Quran emphasizes the importance of sabr and the position of sabireen (those who are patient) in almost 80 verses. Sabr is necessary to achieve inner peace and tranquility, make the best decisions, and receive the best reward in the form of paradise.
