What is the ruling on publishing authentic or good (hasan) hadiths from reliable websites, without knowledge of the the chains of transmission (isnad)? And to what extent is the description of the beards of the Rightly Guided Caliphs accurate?

Publishing authentic prophetic hadiths is among the greatest doors to reward, and their authenticity must be verified by emulating a trustworthy scholar.

The statement that the beards of the Rightly Guided Caliphs were thick is incorrect concerning Abu Bakr al-Siddiq, may Allah be pleased with him, as he had light sideburns (light beard hair). This is what Aisha, may Allah be pleased with her, mentioned in her description of him. However, the beards of others besides Abu Bakr were described as abundant, but the detailed description mentioned in the question has not been reported.
