i.e. an attractive appearance for Allah عَزَّوَجَلَّ, is better than an attractive appearance for the people. (Tafseer Ruh-ul-Bayan, vol. 3, pp. 154)

About having an attractive appearance for going to the Masjid, it is stated in verse 31 of Surah Al-A’raf, part 8:

یٰبَنِیۡۤ    اٰدَمَ   خُذُ وۡا   زِیۡنَتَکُمۡ   عِنۡدَ   کُلِّ   مَسۡجِدٍ

Translation from Kanz-ul-Iman: O children of Aadam! Adorn yourself when you go to the Masjid. (Part 8, Surah Al-A’raf, verse 31)

It is preferable to apply fragrance for Salah

Commenting on the abovementioned verse, Sadr-ul-Afaadil, ‘Allamah Maulana Sayyid Muhammad Na’eemuddin Muradabadi عَـلَيْهِ رَحۡمَةُ الـلّٰـهِ الۡـهَادِی has stated, ‘This dressing in smart clothing. According to another saying, it implies combing the hair and applying fragrance. The Sunnah is to have a smart appearance before offering Salah, because Salah contains supplication to Allah عَزَّوَجَلَّ. So it is Mustahab to have a good appearance and to have fragrance when going for Salah. (Khaza’in-ul-Irfan, pp. 291)

Foul smell of talking in the Masjid

Dear Islamic brothers! This thought may enter the mind that I go to the Masjid for all five daily Salahs in neat and clean clothes by applying fragrance and do not damage the objects etc. lying in the Masjid, that’s why I am protected from spreading foul smells that causes a desecration of the Masjid. So it is a humbly reply to this answer that it is not necessary that only apparent things may bring about foul smells in the Masjid, but the majority of us are suffering from such a disease which we do not even realize, and this disease also becomes a cause of foul smells in our Masajid.

It has been narrated that the people who backbite and talk in the Masjid, the angels complain about them to Allah عَزَّوَجَلَّ due to their foul smell.
