I'm looking for the hadith Musnad 6:421 in English but I can't seem to find it! I have it in Turkish & it's about the consequence of leaving the fardh prayer purposely (being deprived of the protection of Allah). Any help is much appreciated.

The reference is most probably to the Dār al-Fikr Damascus edition of Musnad Aḥmad in 6 volumes. The corresponding hadith in the edition of Shuʿayb al-Arnaʾūṭ et al. (Beirut, 1417–1421/1997–2001) is vol. 45, p. 357, hadith no. 27364.
