Sulayman's Letter to Bilqis

Allah tells us what Sulayman said to the hoopoe when he told him about the people of Saba' and their queen:

قَالَ سَنَنظُرُ أَصَدَقْتَ أَمْ كُنتَ مِنَ الْكَـذِبِينَ

Letters and writings are enough proof on religious matters in the normal circumstances

اذْهَب بِّكِتَابِي هَـٰذَا (Go with this letter of mine - 28). Sayyidna Sulaiman (علیہ السلام) considered it enough to write to the queen of Saba' (Sheba) for the fulfillment of his duty to invite her to faith, and hence sent her a letter. This shows that in the normal circumstances the letter or writing is an acceptable proof. The religious jurists did not accept a letter as an evidence only where a proper personal evidence is required under Islamic law, because testimony is not allowed on telephone or by letter. It has been made mandatory for the witnesses to appear in person before the court. There is a lot of wisdom in this law. Under any law of the world prevalent in any country it is compulsory for the witnesses to appear before the court in person, and the testimony through letter or telephone is not accepted.
