Ruling on the Husseiniyahs of the Raafidis and the sacrifices which are offered on these occasions
Question

                What is the ruling on the Husseiniyahs of the Raafidis and the things that are done there such as slapping and scratching the cheeks, wailing, rending one's garments and beating oneself, sometimes with chains, whilst calling upon the dead and the noble Ahl al-Bayt (members of the Prophet’s household) for help?
Praise be to Allah.This is a great evil and a reprehensible bid’ah (innovation) 
          which should be avoided. It is not permissible to take part in it or 
          to eat the food that is offered on these occasions, because the Messenger 
          of Allaah  (peace and blessings 
          of Allaah be upon him) and his companions (may Allaah be pleased with 
          them) of the Ahl al-Bayt and others did not do that. The Prophet  
          (peace and blessings of Allaah be upon him) said: “Whoever innovates 
          something in this matter of ours (Islam) which is not part of it will 
          have it rejected” (saheeh, agreed upon). And he  
          (peace and blessings of Allaah be upon him) said: “Whoever does an action 
          that is not a part of this matter of ours (Islam) will have it rejected” 
          (narrated by Muslim in his Saheeh, 
          and narrated by al-Bukhaari (may Allaah have mercy on him) in his Saheeh, 
          mu’allaq majzoom). And 
          there are many ahaadeeth with similar meanings. 
 With regard to seeking the help of the dead and the 
          Ahl al-Bayt, this is a form of major shirk, according to the consensus 
          of the scholars, because Allaah says (interpretation of the meaning): 
          
 “And 
          whoever invokes (or worships), besides Allaah, any other ilaah (god), 
          of whom he has no proof; then his reckoning is only with his Lord. Surely, 
          Al‑Kaafiroon (the disbelievers in Allaah and in the Oneness of 
          Allaah, polytheists, pagans, idolaters) will not be successful”[al-Mu’minoon 
          23:117]  
“And the mosques are for Allaah 
          (Alone), so invoke not anyone along with Allaah”[al-Jinn 72:18]  
          
“And who is more astray than one who calls  
          on (invokes) besides Allaah, such as will not answer him till the Day 
          of Resurrection, and who are (even) unaware of their calls (invocations) 
          to them? 
And 
          when mankind are gathered (on the Day of Resurrection), they (false 
          deities) will become their enemies and will deny their worshipping 
          [al-Ahqaaf 46:5-6]  
          
“He 
          merges the night into the day (i.e. the decrease in the hours of the 
          night is added to the hours of the day), and He merges the day into 
          the night (i.e. the decrease in the hours of the day is added to the 
          hours of the night). And He has subjected the sun and the moon, each 
          runs its course for a term appointed. Such is Allaah, your Lord; His 
          is the kingdom. And those, whom you invoke or call upon instead of Him, 
          own not even a Qitmeer (the thin membrane over the date stone).
If you invoke (or call upon) them, 
          they hear not your call; and if (in case) they were to hear, they could 
          not grant it (your request) to you. And on the Day of Resurrection, 
          they will disown your worshipping them. And none can inform you (O Muhammad) 
          like Him Who is the All‑Knower (of everything)[Faatir 35:13-14]
 And there are many aayaat with similar meanings.  
          
The Prophet  (peace 
          and blessings of Allaah be upon him) said: “Du’aa’ (supplication) is 
          a form of worship.” (Narrated by the four authors of Sunan 
          with a saheeh isnaad). And Muslim narrated in his Saheeh, 
          from Ameer al-Mu’mineen ‘Ali ibn Abi Taalib (may Allaah be pleased with 
          him) that the Prophet  (peace and 
          blessings of Allaah be upon him) said: “He is cursed who offers sacrifices 
          to anyone other than Allaah.”  
What 
          is obligatory upon all of the Shi’ah and on everyone else is to worship 
          Allaah alone in sincerity, and to beware of calling upon anyone other 
          than Allaah for help, or of praying to the dead or absent, whether they 
          are from the Ahl al-Bayt or otherwise.  
It is also obligatory to avoid praying to or seeking the 
          help of inanimate objects such as idols, stars, etc., on the basis of 
          the same shar’i evidence (daleel) that we have mentioned above. 
The scholars of Ahl al-Sunnah wa’l-Jamaa’ah, of the Sahaabah 
          and others, are unanimously agreed upon this matter. 
Secondly: what is the ruling on the sacrifices which are 
          offered in those places on these occasions? What is the ruling on the 
          drinks that are distributed in the streets and to the general public? 
          
The answer to this question is the same as the answer to 
          the first question, which is that it is a reprehensible bid’ah and it 
          is not permissible to take part in it, or to eat the meat of these sacrifices, 
          or to drink any of these drinks. If the sacrifices have been made to 
          anyone other than Allaah, from among the Ahl al-Bayt or anyone else, 
          this is major shirk, because Allaah says (interpretation of the meaning): 
          
“Say 
          (O Muhammad): ‘Verily, my Salaah (prayer), my sacrifice, my living, 
          and my dying are for Allaah, the Lord of the ‘Aalameen (mankind, jinn 
          and all that exists). 
He has no partner. And of this 
          I have been commanded, and I am the first of the Muslims’” 
[al-An’aam 6:162-163] 
“Verily, We 
          have granted you (O Muhammad) Al‑Kawthar (a river in Paradise). 
          
Therefore turn in prayer to your 
          Lord and sacrifice (to Him only). 
[al-Kawthar 108:1-2] 
And there are many aayaat and ahaadeeth with similar meanings. 
          
We 
          ask Allaah to help us and you and all the Muslims to do all that He 
          loves and is pleasing to Him, and to grant us and you and all of our 
          brothers refuge from misleading temptations, for He is Ever Near and 
          Ready to respond.
