If you are a beginner then you should only read text with vowel markings (tashkeel), and practice it for a while. After practicing with Arabic text that includes vowels and expanding your Arabic vocabulary, you will be able to recognize/distinguish the words through its context, even if it does not have the vowel markings. Expanding your Arabic vocab is very important before you can read and understand Arabic text without vowel markings.
If you need any help in finding text with vowel markings that you can practice reading, or help in vocab ...etc. Let me know.
