His advocacy extended to encouraging non-Muslims to convert to Islam to integrate into Bruneian society, while also seeking to counter materialistic and consumer-driven cultural trends.

[4] He pursued his education at several notable institutions, including Brunei Town Malay School from 1950 to 1956, Madrasah Aljunied Al-Islamiah in Singapore from 1956 to 1961, and Kolej Islam Malaya in Klang, Selangor, from 1962 to 1967.

[5][4] On 16 March 1983, Badaruddin praised the monarchy for promoting and defending religion, emphasising the importance of implementing Islamic principles in daily life and applauding Brunei's moderation in religious sentiment.

[6] In June 1983, Badaruddin expressed concerns that the public might not fully align their self-interest with the government's development goals, urging citizens to actively participate in progress and contribute to independence.

Badaruddin highlighted the distinct political structure based on the monarchy and the shared experiences of the people, which were vital for maintaining sovereignty and preventing unrest.

Recognising the challenges posed by foreign values, Badaruddin noted that ASEAN membership could foster regional growth and stability while preserving Brunei's unique system.

[5][4] During this time, there were differing views within official circles on the application of the MIB concept, with Badaruddin advocating for a moderate approach to Islam in Brunei, emphasising its role as a unifying force for the nation.

[16] To transform Brunei into a nation aligned with Allah's will, the sultan conceived the idea of Negara Zikir on 19 December 2007,[17] with Badaruddin playing a key role in its development.

He encouraged the sharing of ideas and suggested focusing on maintaining a clean environment, improving business property fee collection, and managing arrears more effectively.

Speaking at the 2014 Literary Essay and Short Story Writing Award Ceremony, he stressed DBP’s role in standardising and promoting Malay as the official language of Brunei since its establishment.

[24] In February 2015, under Badaruddin's leadership, the Ministry of Home Affairs announced that the Brunei government had imposed stringent restrictions on Chinese New Year performances as part of a gradual effort to limit non-Muslim cultural and religious activities in the country.

[a][28] During a royal speech in May 2014, the sultan underlined that the Ministry of Religious Affairs (MoRA), led by Badaruddin, was one of the authorities responsible for putting the SPCO law into effect.

[32] He later criticised remarks made by non-LegCo parties who argued that the increased budget allocation for his ministry was wasteful and impeded the nation's development strategy.

During his motion of adjournment on the final day of the 15th LegCo session on 22 March 2019, he described these views as unwise and unaligned with local ideology, attributing them to a lack of understanding of the national education policy and objectives.

[35] On 1 March 2022, during the fifth day of the 18th LegCo Meeting, Badaruddin warned that social media posts containing disparaging or slanderous remarks against the MoRA could undermine Islamic principles and noted that individuals making such statements might face legal consequences.

His poetry is often analysed using a da'wah theoretical framework, highlighting elements of divine majesty and employing a gentle linguistic style to convey religious messages effectively.

[42] On 6 November 1984, Badaruddin was honoured by Sultan Hassanal Bolkiah with the manteri title of Pehin Udana Khatib, bearing the style Yang Dimuliakan.
