Allama Hilli in his book 'Qawaidul Ahkam' counsels his son Fakhrul Muhaqqiqain in the following words:
"You should practise Sileh Rahmi with the pure descendants of the Sadaat also. The Almighty Allah has emphasized upon this duty so much that he has made the love of relatives of the Holy Prophet (s.a.w.s.) as a compensation of the prophetic mission."
"...Say: I do not ask of you any reward for it but love for my near relatives...."
(Surah Shuara 42:23)
The Holy Prophet (s.a.w.s.) said:
"I shall intercede for four types of people even if they carry the sins of all humanity."
1) A person who has helped my descendants and progeny.
2) A person who has spent his wealth upon my descendants when they were in need.
3) A person who has loved my Progeny with his tongue and his heart.
4) A person who has considered the wants of my descendants when they were surrounded by enemies and were homeless."
Does Anyone Have a Right Upon the Holy Prophet (s.a.w.s.)?
Hazrat Imam Ja'far as-Sadiq (a.s.) said:
"On the day of Qiyamat a caller will announce, 'O people, keep silent, because Muhammad (s.a.w.s.) is to say something to you.' Then the Messenger will arise and say, 'O people! If anyone of you has any right or favour upon me, or if there is any obligation upon my neck then he should stand up. I will see that he is compensated.' The people will reply, 'May our parents be sacrificed upon you. What right? What favour? And what obligation? Rather the rights and favours are of Allah and His Prophet upon all the creatures.'
Goodness to Sadaat and Paradise
Then the Holy Prophet (s.a.w.s.) shall say:
"No, they do have a right. Whoever has provided shelter and help to anyone from my Ahlul-Bayt (a.s.) or did good to them or gave them clothes in their need or fed them when they were in need, should stand up so that I can recompense him."
Some people who had performed such deeds will arise. Then the voice of the Almighty shall be heard. "O Muhammad, my loved one! With due regards to your position I have fixed the reward for their deeds. They shall be given whatever position you intend for them in Paradise." Then Allah shall give them a place near the Holy Prophet (s.a.w.s.) and his Ahlul-Bayt (a.s.) and there would be nothing to obstruct their view."
Rights of the Brothers in Faith
There are numerous traditions in connection with the rights of the believers and brothers-in-faith. A few of such traditions are quoted below:
Mualla Bin-Khanees asked Imam Ja'far as-Sadiq (a.s.): "What are the rights of the believing brother?"
Imam (a.s.) replied,
"Seven rights of the believers are Wajib - If one fails to fulfill even one of these rights, he is externed from Allah's obedience. He shall not receive any reward from the Almighty."
"What are those seven rights?", enquired Mualla.
Imam (a.s.) said,
" I fear that you may fail to act upon them."
Mualla said, "La Quwwata Illa Billah." There is no power except of Allah. (He meant, It wouldn't be so).
Imam Ja'far as-Sadiq (a.s.) said,
"The foremost right is that you wish for the believing brothers whatever you wish for yourself."
Imam (a.s.) then related the other six rights,
"The second right is that you must refrain from angering him and try to seek his pleasure and obey him. The third right is that you help him with you life, your wealth, your tongue, and your hands. The fourth right is that you guide him and teach him that which is beneficial for him. The fifth, is that do not eat till satiation when your believing brother is hungry, and do not drink to satiation if he is thirsty, and do not dress nicely if he is deprived of good clothes. The sixth right is that if you have a servant you should send him to do his work. The seventh right is that if the believing brother says something on oath you should believe him, if he invites, you accept his invitation, if he is sick, visit him, if he dies, accompany his bier, if you come to know any of his needs, fulfill them it before he asks."
(Al Kafi)
Sileh Rahmi with the Imam (a.s.)
Imam Reza (a.s.) has informed,
"Those who cannot come for our Ziarat must visit our virtuous followers. They shall get the reward of performing our Ziarat. And those who wish to do Sileh Rahmi towards us but are unable to do so must do Sileh Rahmi towards our pious devotees. They shall be given the reward of our Sileh Rahmi."
Respect and honour for the believing brother is the same as respect and honour for the spiritual father (Imam [a.s.]). In the same way, insult and disrespect of the believing brother is equivalent to insult and disrespect to the spiritual father, (the infallible Imam [a.s.]). It is for very reason that insulting a believer brings the wrath of Allah upon us and makes us deserving of severe punishment.
We shall conclude with the prayer that Allah may give Tawfeeq to all of us for doing Sileh Rahmi and fulfilling the rights of others.
