Story behind Labubu dolls: Islamic cautious

When Ancient Warnings Become Today’s Headlines: The Labubu Doll Incident & Islamic Wisdom Introduction Some events in our modern lives have an uncanny way of echoing ancient wisdom. Recently, Indian comedian Bharti Singh shared a strange and unsettling experience about her son’s toy — the popular Labubu doll — which she claimed was influencing his behavior. While the entertainment world buzzed with shock and disbelief, those aware of Islamic teachings couldn’t help but connect this to the timeless warnings of Prophet Muhammad ﷺ about keeping lifelike images and statues out of our homes. The Bharti Singh “Labubu Doll” Incident In a video clip that went viral, Bharti Singh revealed that she burned her son Laksh’s Labubu doll after noticing unusual and disturbing behavior from him. What Happened: Laksh, fondly called Golla, began saying strange things like, “Yeh mujhe maarta hai” (“It hits me”). His behavior reportedly changed after playing with the doll. Bh...

महाराष्ट्र का OBT सिस्टम फेल! लाखों छात्रों का भविष्य अंधकार में?

महाराष्ट्र का OBT सिस्टम फेल ! लाखों छात्रों का भविष्य अंधकार में? 📚 क्या था OBT (Open Book Test) और क्यों हुआ फेल? महाराष्ट्र सरकार ने 1st से 9th कक्षा तक  Open Book Test (OBT) लागू किया था, जिसमें छात्रों को किताबें और नोट्स देखकर परीक्षा देने की अनुमति दी गई। इस नीति को लाने का मुख्य उद्देश्य छात्रों का तनाव कम करना और उन्हें रट्टा मारने की बजाय कॉन्सेप्ट समझने पर फोकस कराना था।   लेकिन कुछ ही महीनों में यह योजना पूरी तरह फ्लॉप साबित हुई। ❌ OBT के फेल होने की मुख्य वजहें: 1️⃣ छात्रों में पढ़ाई की आदत खत्म हो गई – क्योंकि उन्हें पता था कि परीक्षा में किताबें देखने की छूट है, इसलिए उन्होंने पढ़ाई में रुचि लेना ही बंद कर दिया।   2️⃣ कॉनसेप्ट समझने की जगह नकल संस्कृति बढ़ गई – शिक्षक और अभिभावक भी मानते हैं कि OBT के कारण छात्रों ने उत्तर रटने की बजाय सीधे किताबों से कॉपी करना शुरू कर दिया।   3️⃣ बेसिक ज्ञान की कमी हो गई – जब छात्र 10वीं में पहुंचे, तो उन्हें 9वीं तक का बेसिक ही ठीक से नहीं आता था, जिससे उनका आगे का करियर प्रभावित हो सकता है। ...
