Qadhi Mohammad Zahid al Hussaini (Allah have mercy on him) said,
‘There are six rights from the rights of Prophethood that are so lofty, superior and essential that without their acknowledgement faith in Prophethood can not be ascertained.’

Below is a summary of them,
1. The Prophethood is eternal
2. The perfections and ranks of Prophethood are bestowed by Allah
3. All of the sayings and states of our Prophet (Allah bless him and grant him peace) portray the faculty of Prophethood
4. Our Prophet (Allah bless him and grant him peace) is the leader (Imam) of all the Prophets
5. The (appropriate) etiquettes and (extreme) reverence of our Prophet (Allah bless him and grant him peace) should be from the depths of one’s heart
6. The love of our Prophet (Allah bless him and grant him peace) must be more than we love our own life, wealth and everything else.
