After a woman gets a divorce from her first husband, she marries another man.
In the second marriage, if she realises and decides that she was better off with her first husband, she can divorce her second husband and then remarry her first husband. It is coming back to the first husband.
That is halala.
In India husbands divorce their wives and then let the women go through this horrendous process for coming back to him. It is if by mistake a Muslim man uttered triple Talaq, then he has left with no other option than to let his wife for marrying with another person and live on his mercy, that he would divorce him immediately and the first husband could get back his wife.
When a Muslim man divorces his wife, she then has to go through halala if she wants to come back to her first husband. That is the twist Indian clerics have given.
