For instance, verse 93 of Qur’an 12 [Surah Yusuf] discusses how Prophet Ya’qub sought Tabarruk from Yusuf’s shirt, it says: “Take this shirt of mine, and cast it upon my father’s face; he will regain his sight, and bring me all your folks.’” Based on the Qur’anic report, when Prophet Ya’qub placed the shirt on his face, he regained his sight: “When the bearer of good news arrived, he cast it on his face, and he regained his sight.” (Qur’an 12: 96).
The acts of both Prophets Yusuf and Ya’qub were an indication to the permissibility of Tabarruk. First, if Tabarruk is not permissible or possible, Prophet Yusuph would not have sent the shirt, and likewise, his father would not submitted to such a request. Similarly, verse 125 of Qur’an 2 [Surah al-Baqarah] reports about the Station of Abraham [Maqām Ibrahim] on which the footprint of Abraham (PBUH) can be seen.
It has been chosen as a place of worship and the people seek Tabarruk from that stone because of that footprint: “And [remember] when We made the House a place of reward for mankind and a sanctuary, [declaring], ‘Take the venue of prayer from Abraham’s Station.’ We charged Abraham and Ishmael [with its upkeep, saying], ‘Purify My House for those who go around it, [for] those who make it a retreat and [for] those who bow and prostrate.’” Therefore, seeking Tabarruk from the seat of the Prophet (PBUHH) and the place of his prayer is permissible.
In a hadith, the place between the Black Stone and Abraham’s station has been introduced as the place where many Prophets of God (PBUT) have been buried and it is therefore considered a blessed place. 2) The Conduct of the Prophet (PBUHH) Apart from the glorious Qur’an, the conduct of the Prophet (PBUHH) or his silent approval is another to establish the permissibility of seeking Tabarruk.
Some hadiths from the Sunni and Shi’a sources indicate that the Holy Prophet (PBUHH) used to encourage his companions to seek Tabarruk or silence when they were doing so. For instance, it is documented that on the night of Lady Fatima’s marriage, the noble Prophet (PBUHH) performed ablution and sprinkled the rest of the water of his ablution on the faces of Lady Fatima (PBUH) and ‘Ali (PBUH) and asked God to bless them and their progeny [2] .
During the Battle of Khaybar when the Prophet wanted to give the flag to Imam ‘Ali (PBUH), he was told that Ali was having a severe eye problem.
