In The Name of Allaah, The Most Merciful The Bestower of Mercy
Ibn Al-Jawzee (rahimahullaah) stated in [Ath-Thabaat Indal Mamaat, page: 11]
And indeed many of the creation become helpless when their loved ones die. So amongst them is one who tears his clothes; and amongst them is one who strikes his face out of despair and amongst them is one who raise objections. And indeed I have seen an old man who reached nearly eighty years of old and he used to strictly guard the congregational prayer. So a son of his died and he said: ‘’It is not befitting for anyone to supplicate, for indeed he will not be answered.’’ He then said: ‘’Indeed Allaah has turned away from us, for He has not left us with a child.’’ So, I realised that his prayers and performance of good deeds was merely a habitual thing, because they were not nurtured upon knowledge and Imaan. These (people) are those who worship Allaah on an edge (i.e. in doubt). [1]

[1] Allaah [The Most High] said: ‘’And among mankind is he who worships Allah on an edge (i.e. in doubt); if good befalls him, he is content therewith; but if a trial befalls him, he turns back on his face.’’ ([Soorah Al-Hajj: Ayah 11]
