Answer
(Fatwa: 417/396/N=1434)
(1) There are four takbirs on Janazah Salah; one should recite Sana after the first takbir, durood after second takbir, while after the third takbir one should recite dua fro oneself, the dead and all Muslims, and then one should turn for salam after the fourth takbir. (al-Durr al-Mukhtar, Ktab al-Salah, Bab Salat al-Janazah 3:109-111)
(2) According to Hanafi and Maliki Fiqh, there is no qirat (recitation from the Quran) in Janazah Salah; therefore sana should be recited after the first takbir, not Surah Fatiha or any other Surah. For evidences and proofs, you can refer to: Hadith aur Ahl Hadith, by Maulan Anwar Khurshid, p 861-876.
