These 12 Rakaats have been specifically enumerated in another narration as: the 2 Rakaats before Fajr, 4 Rakaats before Dhuhr, 2 Rakaats after Dhuhr, 2 Rakaats after Maghrib and 2 Rakaats after Esha. (Sunan Tirmidhi Hadith415). This Hadith is authentic according to Imaam Tirmidhi.
On the day of Qiyaamat, if there be any deficiency in a person’s Fardh Salaat, his Nafl Salaats will compensate for that. (Sunan Tirmidhi Hadith413) – Imaam Tirmidhi has classified this narration as sound.
Therefore, utmost care should be taken in correcting and perfecting our Fardh Salaat by fulfilling all its requirements as well as by being particular of performing the Sunnah Salaat.
The 2 Rakaat Sunnat before the Fardh of Fajr Salaat is the most emphasised Sunnah Salaat of the day (Bukhari Hadith1169, Sahih Muslim Hadith1683, Tahtaawi pg.212)
Sayyidatuna Aaisha (Radhiallaahu Anha) reports that Rasulullah (Sallallaahu Alayhi Wasallam) said. ‘The 2 Rakaats before Fajr are better than the entire world and whatever it contains. (Sahih Muslim Hadith1685)
Regarding the 4 Sunnats before Dhuhr, Rasulullah (Sallallaahu Alayhi Wasallam) mentioned that the doors of the heavens open at that time (Sunan Tirmidhi) and if one follows it up with 4 more Rakaats after the Fardh of Dhuhr (2 Sunnats and 2 Nafl – Fathul Qadeer vol.1 pg.387) Almighty Allah will protect him from Jahannum. (Sunan Tirmidhi Hadith427; Sahih ibn Khuzaymah Hadith1190)
If a person performs 4 Rakaats before Asr Salaat, he will receive a house in Jannah. (Majmauz-Zawaaid vol.2 pg.222). Rasulullah (Sallallaahu Alayhi Wasallam) has made a special Du’aa for the mercy of Allah Ta’aala to be showered on such a person. (Sunan Tirmidhi Hadith430; Sahih ibn Khuzaymah Hadith1193)
Makhool (Radhiyallahu Anhu) reports that Rasulullah (Sallallaahu Alayhi Wasallam) said, ‘If the 2 Rakaats after Maghrib are performed before speaking, it will be lifted high into the heavens. (Al-Maraaseel of Imaam Abu Dawud Hadith73)
If a person performs 4 Rakaats (2 Sunnats and 2 Nafl) after Esha in the Musjid, he will receive the reward of performing these Salaats on Laylatul Qadr. This has been mentioned by various Sahaaba (Radhiallaahu Anhum) – refer al-Musannaf of Imaam ibn Abi Shaybah Hadith7347 – 7353
To perform Witr Salaat is compulsory. Rasulullah (Sallallaahu Alayhi Wasallam) said, ‘Whosoever does not perform Witr Salaat is not among us.’ (Al-Mustadrak vol.1 pg.305-306). Imaam Haakim has classified this narration as Sahih (authentic). (Ibid, also refer to Nasbul-Raayah vol.1 pg.112)
Bearing in mind the abovementioned virtues, every Musallee should endeavour to acquire these benefits by remaining steadfast on the Sunnah Salaats regarding which people are becoming increasingly lax and unmindful these days. Doing so will acquire one the love and assistance of Almighty Allah. (Sahih Bukhari Hadith6502)
