I came across the below today:
Grass, etc. should be placed on the grave of the deceased, as long as it remains fresh it will continue to do tasbīh, it is for this reason that removing fresh grass from the graveyard is disliked (makrūh), just as it is mentioned in Radd al-Muhtār in the chapter of funerals,
“قطع النبات الرطب والحشیش من المقبرۃ دون الیابس کما فی البحر والدرر وشرح المنیۃ وعللہ فی الامداد بانہ مادام رطباً یسبح اﷲ تعالٰی فیونس المیّت وتنزل بذکرہ الرحمۃ ونحوہ فی الخانیۃ انتھی”
“It is disliked to cut fresh grass from the graveyards, not dry grass, just as it is stated in al-Bahr, al-Durr, Sharh al-Munyah, and its reason is mentioned in Imdād; as long as it remains fresh it continues to do tasbīh of Allāh (Most High), due to which the deceased experiences ease, and something similar is mentioned in Khāniyah.”
[Radd al-Muhtār, Bāb Salāt al-Janāiz, Volume 1, pg 606]
Can someone provide more details on the subject.
