Commentary
The object here is that one should not follow one's own view and completely rely on one's own way of thinking, but should follow the sayings of the pious predecessors and the Sahaabah Radiyallahu 'Anhum. This is the general advice of 'Abdullah bin Mubaarak. In respect of all verdicts, whether it refers to the verdicts of justice or otherwise, as has been mentioned. Imaam Tirmidhi has mentioned this as a general advice, this is the view of all the commentators of the Shamaa-il. According to this humble servant, this may have a special relation to this chapter, that the interpretation of a dream is also a verdict, therefore in this too one should not confuse others by giving one's own judgments, but should refer to the interpretation of the learned ones of the past. Many interpretations of dreams have been related from Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. The Sahaabah Radiyallahu 'Anhum and the Taabi'een. The 'ulama of the sciences of interpreting dreams have written, it is necessary for one who interprets dreams to be understanding, pious, cautious and have knowledge of the Qur-aan and Sunnah of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. One should also possess knowledge of the 'Arabic language and its related sciences. Many other conditions and aadaab have been stipulated in books on interpretations of dreams.
