Meaning of the word "URS" from Sahih hadith
The literal meaning of Urs is wedding, and it is for this reason that the bride and bridegroom are called 'Uroos'.
Word Urs in Sahih Hadith
The date of demise of the Friends of Allahعزوجل and Buzurgs is called Urs because, whih the angels who question in the grave (Nakeerain) test the deceased and find him to be successful, they say, "Sleep like a bride who will not be awakened by anyone except for the person who is most beloved to her."
Reference : [Mishkaat, Baabu Ithbaatil-Qabr]
Because these angels have called them 'Uroos' on that date, it therefore becomes the day of 'Urs',
Another reason is because, on this day, the angels will reveal the beauty and splendor of Rasoolullahصلی اللہ علیہ وسلم and ask him, "What did you say about this man?" He will reply, "He is the Uroos (adorned personality) of all creation. The entire creation has attained splendor through him." Meeting the beloved is the day of 'Urs', and it is for this reason that the day is called Urs.
Allama Tahtawi (radi Allahu anhu) states: "Some among our preceeding Ulama have given a legal verdict that the action of placing flowers or fresh branches is Sunnat and is proven from Hadith".
Wet grass should not be removed from the grave because the wet grass prays the Tasbih of Allah Taala and gives solace to the buried. If it is removed then you have committed an unjust deed for the deceased.
Imam al-Dhahabi said: "Ahmad ibn Hanbal was asked about touching the Prophet's grave and kissing it and he saw nothing wrong with it. His son 'Abd Allah related this from him. If it is asked: "Why did the Companions not do this?" ]We reply: "Because they saw him with their very eyes when he was alive, enjoyed his presence directly, kissed his very hand, nearly fought each other over the remnants of his ablution water, shared his purified hair on the day of the greater Pilgrimage, and even if he spat it would virtually not fall except in someone's hand so that he could pass it over his face. Since we have not had the tremendous fortune of sharing in this, we throw ourselves on his grave as a mark of commitment, reverence, and acceptance, even to kiss it. Do you not see what Thabit al-Bunani did when he kissed the hand of Anas ibn Malik and placed it on his face saying: "This is the hand that touched the hand of the Messenger of Allah "? Muslims are not moved to these matters except by their excessive love for the Prophet , as they are ordered to love Allah and the Prophet more than their own lives, their children, all human beings, their property, and Paradise and its maidens. There are even some believers that love Abu Bakr and 'Umar more than themselves.
"'Abd Allah ibn Ahmad said: "I saw my father take a hair that belonged to the Prophet , put it on his mouth, and kiss it. I believe I saw him put it on his eyes. He also dipped it in water and drank the water to obtain cure. I saw him take the Prophet's bowl (qas'a), wash it in water, and drink from it. I saw him drink Zamzam water in order to seek cure with it, and he wiped his hands and face with it." I say: Where is the quibbling critic of Imam Ahamad now?
It is also authentically established that 'Abd Allah asked is father about those who touch the pommel of the Prophet's e pulpit and touch the wall of the Prophet's e room, and he said: "I do not see any harm in it." May Allah protect us and you from the opinion of the Khawarij and from innovations!
[ Al-Dhahabi, Siyar A'lam al-Nubala' (9:457). Ch. on Imam Ah.mad, section entitled Min adabih]
He states: there are diverse opinions amongst the scholars regarding kissing graves. It is an act which lies between two things: something that allows the practice: love and something that disallows it: adab respect.Hence, the one who does it through overwhelming love is not criticized because this act is proven from the sahabah. Though, it is better for the general public to be precautious.] Our scholars have explicitly stated that one should stand at least four feet away from the grave, so how would one kiss it!?
QUESTION: What do the Ulamaa-e-Deen and Muftiyaane Share-Matin say regarding kissing the grave of Awliyaa-e-Kiraam and doing the tawaaf of the grave and doing sajdah before the grave (give written answer and earn sawaab)
ANSWER: No doubt doing the tawaaf of anything else except the Kaabah Muazzamah is unlawful [haram] .Sajdah (prostration) in front of anyone else except Allah is forbidden in our Shariat and about kissing the grave there are differences about it among the Ulamaas It is allowed and proved from Hadiths and even Salafs But seeing the modern fitna and ahle biddah [innovators] spreading false stories about ahlus sunnah and showing it as people are doing sajda to graves when they kiss the ground or grave only ,
