I've opted Islamic History Part-1 in Combined Competetive Examination-2018, SPSC. Since no one seems to be replying in the SPSC section, I thought I should ask for help here. Can anyone suggest me a concise book or any other source? I need to cover the syllabus in 15-20 days.
SYLLABUS:
1. Pre-Islamic Arabia
2. The Holy Prophet and Orthodox Caliph
3. The Umayyad Period
