Muslim Groups differences Criticism,what ideal response

Only Allah can give the strength and Hidayat.

1.A Muslim has to/must ask Allah often for guidance about things on which there is a difference of opinion,

2.He should seek the truth without groupism and fanaticism,

3.To cooperate with those who work for Islam on whatever truth they are upon and not to imitate them if they deviate from the truth.

4.Nobody is infallible after the Prophets.  The words and actions of every person could be accepted or rejected.   

5.However, we have to advise with wisdom whoever deviates from the truth, and explain to him the truth with the best manners.

6.In addition to this, we draw every muslim attention to the fact that we should be keen in educating ourself, by learning what is required of Aqeedah and Islamic rulings.
7.To know that Allah has a right upon him, his body (soul) has a right upon him, and his wife (and family), has a right upon him, so he has to give the right of everybody.  

8.He has to benefit from the point of view of others on himself, and not to be content with oneself, and not to call to Allah except with something he is sure about, that it is from Allah and His Prophet (Sallallahu Alaihi wa Sallam).

9.In every criticism there is a either a lesson or reward for Akhirah.Because if you will do sabr (Patience) on baseless allegation Allah will surely give you Reward. Be sure of it .It is prophets word.

The Tablighi Jamaat elders (other call leaders) at Markaz Hazrat Nizamuddin,India (R.A.)  have a written policy of not indulging in any argument and counterarguement and defence.

Maulana Inamul Hasan (R.A.)(d 1995) the former Amir of Tableeghi Jamaat has said.

"It is better that in case the objections and allegation are correct, rectify them. Whereas if they are wrong ,have patience (leave the matter to Allah)."

MAULANA  has further said.....
"If you reply they will give a rejoinder. You reply again they will issue another rejoinder. It will continue like this and no purpose will be served."

We have to supplicate a lot with the supplication that the Prophet (Sallallahu Alaihi wa Sallam) used to make at the beginning of the night prayer which is: “O, Allah! Lord of Jibreel, Mikaael, and Israafeel, Creator of the Heavens and the Earth, Knower of the Seen and the Unseen, You are the Arbitrator between Your Servants in that which they have disputed.  Guide me to the truth by Your leave, in that which they have differed, for verify You guide whom You will to the straight path.”
