It is also proven by Sahih (authentic) Ahadees that they perform Hajj
and offer Salah in their graves. Sayyiduna Anas رَضِىَ اللهُ تَعَالٰی عَـنْهُ has narrated
that the Most Blessed and Holiest Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has said, ‘اَلۡاَنۡۢبِيَاءُ اَحۡيَاءٌ فِي قُبُوۡرِهِمۡ يُصَلُّوۡنَ i.e. the Prophets are alive in their graves and they offer Salah.’ (Musnad Abi Ya’la, vol. 3, pp. 216, Hadees 3412)

Sayyiduna Imam Manawi عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی has stated that this is a Sahih (authentic) Hadees. (Fayz-ul-Qadeer, vol. 3, pp. 239)

Let’s listen to a few parables of the Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم helping the People from his Ummah after his apparent demise.

v  Sayyiduna Shaykh Ahmad Bin Nafees عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی has stated, ‘During my stay in Madina-tul-Munawwarah, I once experienced extreme hunger. Presenting myself at the blessed tomb of the Holy Prophet
صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, I pleaded, ‘Ya Rasoolallah صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم! I am hungry.’ Suddenly, I fell asleep. Meanwhile, someone awoke me and asked me to go with him. I agreed so he took me to his home. Serving me with dates, butter and wheat bread he said, ‘Eat until you are satisfied because my blessed ancestor Sayyiduna Muhammad صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has commanded me to be hospitable to you. Come to me whenever you feel hunger in future.’ (Hujjah-tul-Ilahi-‘alal-‘Alameen, vol. 2, pp. 573)

بے مانگے دینے والے کی نعمت میں غرق ہیں

مانگے سے جو مِلے کِسے فہم اس قدر کی ہے

v  Sayyiduna Ahmad Bin Muhammad Sufi رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has said that I continued to wander in the jungles for three months until my skin became very thin and weak. Finally I reached Madinah Munawwarah and made my Salam in the blessed court of the Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم and Shaykhayn Karimayn (Sayyiduna Abu Bakr Siddeeq رَضِىَ اللهُ تَعَالٰی عَـنْهُ and Sayyiduna Umar-e-Farooq رَضِىَ اللهُ تَعَالٰی عَـنْهُ) and then fell asleep. In a dream I had the privilege of the vision of the Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم.
