There are several narrations which indicate that the prophets (peace be upon them) were interceding to Almighty Allah by the five Infallibles (the Final Prophet, Ali, Fatimah, Hasan and Hussain, peace be upon them all). Other texts indicate that their Noor preceded the creation of everything else in glorifying the Almighty Allah. This is an indication of their superiority over the rest of the creation.
Based on compulsory precaution, one should not desert a believer for more than three days, even if the latter was wrongful to him. It is sufficient to satisfy this obligation by greeting him (e.g. saying 'salam alaykum'). If the other party insisted on the abandonment, he will become the deserter. This prohibition has three exceptions: First: if the desertion was to forbid the wrong. Second: if the desertion would lead to a benefit that the Sharia recommends, like - for example - if desertion leads to paying attention towards a truth that could remain hidden without such desertion, or similar cases. Third: if the reestablishing the relationship would lead to demeaning oneself. One should be careful in not confusing arrogance and anger with self-demeaning.
