There can be no doubt that laughing too much has an effect on the Muslim’s heart and distracts him from thinking deeply and fearing Allaah.
The Messenger (peace and blessings of Allaah be upon him) warned us against laughing too much, and told us of the danger it poses to the heart. Here is the Hadith about laughing too much in Arabic and English meaning.
Hadith About Laughing Too Much
It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: “Do not laugh a lot, for laughing a lot deadens the heart.”

Hadith About Laughing In Arabic Text
عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ “ لاَ تُكْثِرُوا الضَّحِكَ فَإِنَّ كَثْرَةَ الضَّحِكِ تُمِيتُ الْقَلْبَ ”
There is no specific du’aa’ that has been narrated for dealing with this particular problem. Rather you can call upon Allaah in whatever words you wish and ask Him, for He is the All-Hearing and Ever-Responsive, to relieve you of this problem and to give you a heart that is humble before Him and a tongue that remembers Him and an eye that weeps with fear of Him.
You should also read Qur’aan a great deal and ponder its meanings, and remember Allaah a great deal, make du’aa’ and turn to Him in all your affairs.
We ask Allaah the Almighty, Lord of the Mighty Throne, to heal you and all the Muslims who are sick.
