Sayyed belongs to the family tree of the Prophet Muhammad (SAWA), that is why he should respect and act upon the teachings of the Prophet (SAWA) and Ahlul Bayt (AS).
Pious Sayyeds have great rule in history of Muslims in spreading the message of Islam in many countries. Great number of our Maraaji' of Taqleed, leading scholars, authors and teachers are Sayyeds.
Some of the scholars stated that the good deeds of Sayyed will have more reward, while bad deeds from him will cause him more hardship. They mention the Quranic verse 33:30 ( يضاعف لها العذاب ضعفين )as an evidence which states doubling the punishment of the sins if committed by a wife of the Prophet (SAWA). Sayyeds should keep the respect of the Prophet (SAWA) and Ahlul Bayt (AS) in their behavior.
Every Muslim must respect the Sayyeds and help them as far as he can.
The Prophetic Hadeeth states: Love Allah, for His bounties on you, and love me for the love of Allah, and love my Progeny (Ahlul Bayt) for my love.
We have many Hadeethes encouraging Muslims to be kind, co-operative, helpful and respecting Sadaat (Sayyeds) being from the family tree of the Prophet (SAWA).
