Is what is meant by hastening the deceased to the lahd (niche in the grave) the hastening of his preparation, prayer over him, and burial, or hastening him to burial after praying over him?

The hadith "Hasten with the Janazah (funeral bier)" is interpreted as hastening one's pace when carrying it to the grave, which is the view favored by An-Nawawi. It may also be understood as hastening its preparation, including washing, praying over, and burying it, which Ibn Hajar supported with the hadith, "When one of you dies, do not detain him, but hasten him to his grave." The more apparent understanding is that the hadith encompasses both matters, provided that the necessary requirements of the situation are not violated.
