All those believing in oneness of Allah, true Muslims are granted pardon and forgiven for their sins, save those two persons who have enmity and grudge against each other, as such on Thursday’s keep the hearts and soul clean and purified with grudge against none. It is good fasting on Thursday, as on this day deeds and acts are presented before Allah.
(Saheeh Muslim)

As for as possible begin the journey on Thursday.
(Saheeh Bukhari)
