Arabic hadith text
وَعَنْ جَابِرٍ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَن تجصص الْقُبُور وَأَن يكْتب لعيها وَأَن تُوطأ. رَوَاهُ التِّرْمِذِيّ
Translation
Jabir said God’s messenger forbade that graves should be plastered with gypsum, have any writing on them, or be trodden on. Tirmidhi transmitted it.
