On the virtues of Jumu'ah, eminent scholars have written books including Allama Suyuti(rahmatullahi alaiyh). In one of his books, he stated that whoever dies on Jumu'ah(day or night) ie. [Thursday night after Maghrib to - before Maghrib of Friday] is not interrogated in the grave.
Hakeem and Tirmizi(rahmatullahi alaiyhum) have stated that it is clear what position a person is granted by Allah when a person dies on Jumu'ah. Hell(Jahannam) is not lighted on that day and it's days are shut down. Hence, death on Friday is auspicious because it is granted to those only whose destiny has been fixed as auspicious.
According to Allama Suyuti(rahmatullah alaiyh), a man who dies on Jumu'ah, is rewarded a martyr and is exempted from interrogation of the grave. (Sharhassadur)
It is stated by Sayyidina Jabir(radhiyallahu anhu) that the Prophet(sallallahu alaiyhi wassallam) said that whoever dies on Jumuah is saved from the tribulation of the grave and will come bearing the signs of martyrs on the Day of Judgement. (Hulia, Abu Naim)
According to Sayyidina Ayaas bin Bakeer(radhiyallahu anhu) , the Prophet(sallallahu alaiyhi wassallam) has said that whosoever dies on Friday day or night, is granted reward of the martyr and is saved from the trial of the grave. (Targheeb)
Sayyidina Ibn Umar(radhiyallahu anhu) reported that the Prophet(sallallahu alaiyhi wassallam) said that, if a believer dies on Friday, Allah exempts him from the trial of the grave. There is such a moment on that day that prayers are granted. The sins of the believers are rubbed off and one years compensation is awarded for every step towards the Masjid for Jumu'ah prayer. Friday is the most virtuous day of the week and all the souls assemble and introduce one another. (Ahmad, Tirmizi, Baiyhaqi)
Sayyidina Akrama bin Khalid(radhiyallahu anhu) reported that the Prophet(sallallahu alaiyhi wassallam) said that whoever dies on Friday day or night dies in perfect belief and is saved from the tribulations of the grave. (Baiyhaqi)
Allama Qurtubi(rahmatullahi alaiyh) mantains that these narrations are not contradictory of those in which interrogation of the grave is mentioned. But it makes it clear that Allah has exempted certain servants whom He is pleased and it is Allah's discretion only and is not subject to questioning and ALLAH IS MOST JUST AND KNOWS BEST.
