Do not crack your fingers during the prayer .

The hadith of Ali ibn Abi Talib states that the Prophet Muhammad (peace be upon him) advised against cracking one's fingers during prayer. This is an important reminder to Muslims that they should remain focused and mindful while praying and not engage in any distracting activities such as finger cracking. It is also a reminder to maintain proper etiquette while engaging in religious activities and to respect the sanctity of prayer by avoiding any unnecessary movements or sounds. Furthermore, this hadith serves as a reminder for Muslims to take their prayers seriously and strive for spiritual growth through their worship of Allah.
