If your syllabus explicitly recommends it (common in Indian universities), buy it – but also borrow Understanding Analysis from the library. If you are self-studying, start with Abbott, then use Malik & Arora for extra problems and advanced topics.
“Mathematical Analysis by Malik & Arora” is a workhorse, not a showhorse. It will serve you well if you are willing to work through its dense pages and already have some mathematical maturity. For a beginner, pair it with an intuitive text like Abbott or a video course (e.g., MIT OCW). For exam cramming and reference, it is excellent value for money.” mathematical analysis by malik and arora
