Listen attentively to teachings from Prophet Muhammad PBUH , avoid practices which are displeasing to Allah SWT , remain focused during prayers .

This hadith speaks about an incident between Hasan ibn Ali and AbuRafi', a freed slave of Prophet Muhammad. It was narrated that when Hasan was standing in prayer, he had tied a back knot in his hair. Upon seeing this, AbuRafi' untied it and reminded him to concentrate on his prayer instead. He then explained that he heard from Prophet Muhammad that tying a back knot in one's hair is considered to be a seat for Satan. This hadith serves as an important reminder for Muslims to avoid such practices as they are not pleasing to Allah SWT and can lead us astray from our faith if we do not take heed. It also teaches us to remain focused on our prayers and not get distracted by other matters while praying, so we can reap its full rewards.
