Seeking Blessing from the Persons of Other Than the Prophets

Question:
Is it established in the Sunnah that intrinsic blessing may exist in other than the prophets?

Answer:
We know of nothing in this except what is established regarding him (peace and blessings be upon him) that Allah placed in his body, his sweat, and the touching of his body a special blessing specific to him (peace and blessings be upon him), and no one else, such as scholars or others, is to be compared to him in this regard.
And what some people do of seeking blessing from some people is an error with no basis, and there is no evidence for it. This is specific to the Prophet (peace and blessings be upon him); because Allah placed blessing in his sweat, in his saliva, in his ablution, and in his hair (peace and blessings be upon him). For this reason, he distributed his hair among the people during the Farewell Pilgrimage, and he ordered the Companions to take from the surplus of his ablution and from his sweat (peace and blessings be upon him) due to the blessing Allah placed in it. No one else is to be compared to him in this; for this reason, the Companions did not seek blessing from al-Siddiq, nor from 'Umar, nor from 'Uthman, nor from 'Ali, and they are the best of people after the prophets. This indicates that this is specific to the Prophet (peace and blessings be upon him).
As for what some people do of seeking blessing from some scholars, or from some worshippers, or from some walls of the Ka'bah, or from the covering of the Ka'bah, all of this has no basis. Rather, it must be prevented.
