Mourning Imam Hussein
Question :

Is mourning Imam Hussein (peace be upon him) permissible or recommended?

Answer :

The commemoration of the Ahlulbait (Peace be upon them) is amongst the best deeds that the religious texts have emphasized on, and it is narrated that there are great rewards for those who perform it.

Commemoration the Tragedy of Karbala
Question :

I am a Shia, and I have come across criticism about how the Shias commemorate the tragedy of Karbala and the ways of mourning for Imam Hussain (peace be upon him) and his family and companions. How can we explain to them the reasoning and purpose behind this?

Answer :

What the lovers of the Ahlulbait (peace be upon them) do in the acts of mourning is expressing their grief and pain for what happened to Imam Hussein and his household on the day of Ashura. It is not something strange. It is, rather, an expression of the love and loyalty that Almighty Allah has ordered the Islamic nation to hold when He said: "Say (O , unto mankind): I ask of you no recompense for this, except love for the kinsfolk." (23:42). Sunnis and even non-Muslims participate in these commemorations since the loyalty to the Ahlulbait and loving them is not limited to the Shia.
These commemorations are not a tradition but it is an implementation of the orders of the Imams of the Ahlulbait to their followers, when they ordered them to hold such commemorations. It is narrated that Imam Ja'afar al-Sadiq (peace be upon him) said: "Enliven our commemoration. May Allah have mercy on those who enliven our commemorations". There are many other such narrations.
Yes, people and nations differ in their expressions of sadness, since the aim is to commemorate these tragic incidents, as means of sharing their grief and sorrow.

Lamentation
Question :

I have a Sunni friend who asked me why Shias mourn mainly for Imam Hussein (peace be upon him) whereas there were many martyrs in Karbala?

Answer :

Shias mourn all the martyrs of Karbala. They remember their faithful dedication to sacrifice themselves with praise and respect, whether they were among the Ahlulbait or among the other companions. It is customary in some Shia communities to specify a day within the first ten days of Muharam to remember one of the martyrs of the companions of the Imam as well as a specific day for Abbas bin Ali (peace be upon him) and other members of the Ahlulbait.
The Ziyarats that were narrated from the Ahlulbait (peace be upon them), were specified for Imam Hussein (peace be upon him), while they also mention the companions with praise and Salam. It is natural that Shias will mainly mourn for Imam Hussein (peace be upon him) since he was the Imam and the rest were his followers and companions, in addition to his relation to the Messenger of Allah (peace be upon him and his holy progeny).

Black Clothing
Question :

Is it true that wearing black clothing is disliked? If so, does this also apply when wearing black clothes to mourn the tragedies of the Ahlulnait (peace be upon them)?

Answer :

It is reported in religious texts not to wear black clothes, which suggests that it is disliked to do so. However, there is no doubt that it is preferable to wear black clothes to mourn what happened to Imam Hussain (peace be upon him) and his household and companions as this represents loyalty and love for the Ahlulbait (peace be upon them).

Models of Shrines
Question :

Can we keep models of the shrines of the Imams (peace be upon them) in our homes and mosques, and seek our wishes from them?

Answer :

It is permissible to seek the blessings from whatever is related to the Prophet and the Imams (peace be upon them all). Seeking one's wishes from them is basically seeking intercession from them because of their high rank and closeness to Almighty Allah.

Rituals of Commemorating
Question :

There are various opinions amongst the Shia about some rituals of commemorating the Ahlulbait (peace be upon them) and mourning for them, and these differences become more apparent in the month of Muharram. What is your advice in this regard?

Answer :

There is no doubt that we should commemorate the tragedy of Ashura and express our grief and sorrow over what happened to Imam Hussein (peace be upon him) and his family and companions; and the Imams (peace be upon them) emphasized this in a well-known manner that is recorded in the books of narrations.
However, differences have occurred in respect to some practices and rituals, and opinions have differed about them for some time.
Our advice to all the believers is that they should refer in this issue to those Maraji who they follow and fulfill the conditions of Taqleed, and they should distance themselves from conflicting and quarrelling over it, as a believer may commit a sin as a result of such arguing. Rather, it is best at times to leave such quarrelling when there is no benefit in it. This may even cause harm and lead to animosity and hostility between believers.

20th of Safar
Question :

Regarding commemorating Arba'een and performing the recommended acts of that day, should one do it on the 20th of Safar or actually 40 days after the Day of Ashura for that year? They are always not the same because the Islamic month can be either 29 or 30 days. For example, this year, the 20th of Safar is only 39 days after Ashura in the United States.

Answer :

It is recommended to perform the acts of Arba'een on the 20th of Safar.
