Is raising one's voice in ذكر (remembrance of God) after prayer, especially Fajr prayer, considered a sound Sunnah based on the Hadith of Ibn Abbas, despite the disturbance this may cause to others, and are others obliged to raise their voices as well?

The jurists differed on raising the voice in dhikr (remembrance of Allah) after prayer. The reason for this difference stems from what Ibn Abbas narrated, that raising the voice in dhikr after the prescribed prayer was practiced during the time of the Prophet, peace and blessings be upon him. Some jurists, such as Al-Tabari, Ibn Hazm, and Shaykh al-Islam Ibn Taymiyyah, held that it is a Sunnah, citing the Hadith of Ibn Abbas and other proofs. Others disliked it, stating that the Prophet, peace and blessings be upon him, did not consistently practice it, but rather did it for teaching purposes and then abandoned it. This is the view of Imam Al-Shafi'i and the majority.

Shaykh Ibn Uthaymeen favored its desirability, maintaining that vocalizing it does not contradict other verses and hadiths, and that any disturbance might be alleviated by habituation or by moving away from the worshiper, emphasizing that the vocalization should be without causing annoyance.
