*   Letting the mind wander here and there during salah and not trying to offer it with full concentration.^[1] 

Alas! In today’s day and age, people miss salah merely due to laziness, but the same laziness quickly transforms to vigour when it comes to committing sin. There are even some people who deliberately do not offer salah for weeks or months just because they missed one salah or a few. If an Islamic brother tries to encourage such a person to offer salah, he responds: “اِنْ شَــآءَالـلّٰـه I will start offering salah again from the following Friday”, or, “I will start offering salah regularly from the month of Ramadan.” Thus, they مَعاذَ الـلّٰـه boldly acknowledge without any shame that they will continue to commit the major sin of missing salah until Friday or the month of Ramadan. Undoubtedly, this is the consequence of having no fear of Allah, nor the yearning for worship; otherwise, one who fears Allah in his heart and yearns to worship offers salah regularly at all costs and refrains from the disobedience of Allah. Do not forget that missing salah deliberately is a major sin, haram and an act that leads to Hell. In verse 59 of Sūrah Maryam, Allah Almighty has stated:

فَخَلَفَ مِنۡۢ بَعۡدِہِمۡ خَلۡفٌ اَضَاعُوا الصَّلٰوۃَ وَ اتَّبَعُوا الشَّہَوٰتِ فَسَوۡفَ یَلۡقَوۡنَ  غَیًّا (ۙ۵۹)

Translation from Kanz al-Īmān: So, after them in their place came those unworthy successors who missed salah and pursued their lusts; so, they will therefore soon encounter the jungle of Ghayy in Hell (i.e. a dreadful valley in the Hellfire).^[2]
