The Noble Scholar Shaykh Ibn Baaz (may Allah have mercy upon him) stated:
That which is obligatory upon the believer is to stay away from the prohibitions of Allāh. The acts of disobedience are prohibited at all times and in all places. However, in this noble month (Ramaḍān), it’s obligatory that staying away (from that which Allāh has prohibited) is even more so. It’s obligatory that the believer strives in preserving his fast and protecting it from the rest of the acts of disobedience; from the likes of backbiting, tale carrying, oppression of the people, transgression against them in any matter regarding their wealth or their persons and other than that from the acts of disobedience. Also (we are to stay away from) the likes of consuming interest, deception in business dealings and other than that from the acts of disobedience from that which Allāh has prohibited. Therefore, the believer must stay away from every act of disobedience of Allāh, keep far from it, hope for the reward of Allāh and fear the punishment of Allāh. He is to strive in fulfilling the obligations of Allāh. He makes the prayer in congregation and preserves it (by making it) in all of its five legislated times. He is to be dutiful to his two parents and keep the ties of kinship. He is to call to Allāh, command the right and forbid the wrong. He is to stay away from all evil and strive in (doing) all good, especially in this noble month. The month of Ramaḍān is the month of charity, the month of standing at night in prayer and the month of rewards for good deeds being increased. Therefore, the believer strives in taking advantage of these days and nights with fasting (during the day) and standing at night in prayer.
