Flames of fire in grave

Sheikh-e-Tareeqat, Ameer-e-Ahl-e-Sunnat, founder of Dawat-e-Islami, ‘Allamah Maulana Abu Bilal Muhammad Ilyas Attar Qaadiri Razavi Ziyaee   دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـه mentions an admonitory parable on page no. 20 of his booklet “Kafan Choron ke Inkashafat” [Disclosures from shroud thief]: A man’s sister died. After he returned having buried her, he recalled that his pouch of money had dropped into her grave. So he came to the graveyard to dig it out from the grave. When he dug the grave open, he saw a terrifying scene. The flames of fire were blazing in the grave of his sister. He quickly filled up the grave and rushed to his mother and asked, ‘Dear mother! What were the deeds of my sister?’ She said, ‘Son! Why are you asking?’ He replied, ‘I have seen flames of fire blazing in her grave.’ On hearing this, his mother began to cry and said, Alas! ‘Your sister was sluggish in Salah and would offer Salah after the stipulated time (i.e. she used to offer Salah after making it Qada).’ (Mukashafa-tul-Quloob, pp. 189)

صَـلُّوا عَلَى الْـحَـبِيْب                                                                                                                 صَـلَّى الـلّٰـهُ تَـعَـالٰى عَـلٰى مُـحَـمَّد

Dear Islamic brothers! We come to know from the aforementioned narration that being lazy in offering Salah is a very big sin and a cause for the punishment of grave. We shall also offer all five Salahs with full enthusiasm in Masjid with Jama’at and not observe laziness in Salah at all.

Being lazy in Salah is a sign of hypocrites. When hypocrites used to stand for Salah with Muslims, they used to be lazy in doing so. The reason because their hearts were void of Iman [faith], hence, they were unable to relish the pleasure of worship. They used to offer Salah just to show off to people. Allah Almighty says regarding them in 142^nd Ayah of Surah Nisa, Part 5:

وَ اِذَا قَامُوْۤا اِلَى الصَّلٰوةِ قَامُوْا كُسَالٰىۙ

Translation from Kanz-ul-Iman: And when they stand up for Salah, they do it unwillingly.

Under this Ayah, it is written in Tafseer Siraat-ul-Jinaan: Not offering Salah, offering it in front of people but not when alone,
