Hasan bin Saif (may Allah have mercy on him) says that Hasan Basri (may Allah have mercy on him) was asked: Is it permissible to put dots on the Mushaf in Arabic? He replied: There is no harm in it. Have you not received the statement of Sayyiduna Umar (may Allah be pleased with him) that he wrote: Learn Arabic, gain understanding of the religion, and interpret dreams in a good manner? Abu Raja Muhammad bin Saif (may Allah have mercy on him) says: I asked the Tabi'i Muhammad bin Sirin (may Allah have mercy on him) about this, and he replied: I fear that you might add to the letters.
